-
-   *    WARNING
-	-------
-	This is alpha-test software.  It is not guaranteed to work. As a
-	matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
-	would like to hear from you if you use this driver, even if it works.
-	If it doesn't work, be sure to send me a mail with the problems !

-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
-    Most of this driver, except for ultramca_probe is nearly
-    verbatim from smc-ultra.c by Donald Becker. The rest is
-    written and copyright 1996 by David Weis, weisd3458@uni.edu
-
-    This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
-    This driver uses the cards in the 8390-compatible, shared memory mode.
-    Most of the run-time complexity is handled by the generic code in
-    8390.c.
-
-    This driver enables the shared memory only when doing the actual data
-    transfers to avoid a bug in early version of the card that corrupted
-    data transferred by a AHA1542.
-
-    This driver does not support the programmed-I/O data transfer mode of
-    the EtherEZ.  That support (if available) is smc-ez.c.  Nor does it
-    use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
-    Changelog:
-
-    Paul Gortmaker	 : multiple card support for module users.
-    David Weis		 : Micro Channel-ized it.
-    Tom Sightler	 : Added support for IBM PS/2 Ethernet Adapter/A
-    Christopher Turcksin : Changed MCA-probe so that multiple adapters are
-			   found correctly (Jul 16, 1997)
-    Chris Beauregard	 : Tried to merge the two changes above (Dec 15, 1997)
-    Tom Sightler	 : Fixed minor detection bug caused by above merge
-    Tom Sightler	 : Added support for three more Western Digital
-			   MCA-adapters
-    Tom Sightler	 : Added support for 2.2.x mca_find_unused_adapter
-    Hartmut Schmidt	 : - Modified parameter detection to handle each
-			     card differently depending on a switch-list
-			   - 'card_ver' removed from the adapter list
-			   - Some minor bug fixes

+    Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
     Verified to work with up to 2 DE212 cards in a system (although not
       fully stress-tested).
 
-    Currently known bugs/limitations:
-
-    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
-           not the command line for IRQ and memory address.  You can
-           specify them if you want, but it will throw your values out.
-           You still have to pass the IO address it was configured as

-                    : request_irq() and free_irq(). Just NULL for now.
-
-  Mike Cruse        : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
-                    : in net_open() and net_close() so kerneld would know
-                    : that the module is in use and wouldn't eject the
-                    : driver prematurely.
-
-  Mike Cruse        : Rewrote init_module() and cleanup_module using 8390.c
-                    : as an example. Disabled autoprobing in init_module(),
-                    : not a good thing to do to other devices while Linux
-                    : is running from all accounts.
-
-  Russ Nelson       : Jul 13 1998.  Added RxOnly DMA support.

-                    : Folded in changes from Cirrus (Melody Lee
-                    : <klee@crystal.cirrus.com>)
-                    : Don't call netif_wake_queue() in net_send_packet()
-                    : Fixed an out-of-mem bug in dma_rx()
-                    : Updated Documentation/networking/cs89x0.txt

-   net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
-   This is an extension to the Linux operating system, and is covered by the
-   same GNU General Public License that covers that work.
-
-   Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
-   This is basically Michael Hipp's ni52 driver, with a new probing
-   algorithm and some minor changes to the 82586 CA and reset routines.
-   Thanks a lot Michael for a really clean i82586 implementation!  Unless
-   otherwise documented in ni52.c, any bugs are mine.
-
-   Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
-   any way.  The ni52 is a lot easier to modify.
-
-   sources:
-   ni52.c
-
-   Crynwr packet driver collection was a great reference for my first
-   attempt at this sucker.  The 3c507 driver also helped, until I noticed
-   that ni52.c was a lot nicer.
-
-   EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
-   Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
-   stuff.  Information on CardFacts is found in the Ethernet HOWTO.
-   Also see <a href="http://www.3com.com/">
-
-   Microprocessor Communications Support Chips, T.J. Byers, ISBN
-   0-444-01224-9, has a section on the i82586.  It tells you just enough
-   to know that you really don't want to learn how to program the chip.
-
-   The original device probe code was stolen from ps2esdi.c
-
-   Known Problems:
-   Since most of the code was stolen from ni52.c, you'll run across the
-   same bugs in the 0.62 version of ni52.c, plus maybe a few because of
-   the 3c523 idiosynchacies.  The 3c523 has 16K of RAM though, so there
-   shouldn't be the overrun problem that the 8K ni52 has.
-
-   This driver is for a 16K adapter.  It should work fine on the 64K
-   adapters, but it will only use one of the 4 banks of RAM.  Modifying
-   this for the 64K version would require a lot of heinous bank
-   switching, which I'm sure not interested in doing.  If you try to
-   implement a bank switching version, you'll basically have to remember
-   what bank is enabled and do a switch every time you access a memory
-   location that's not current.  You'll also have to remap pointers on
-   the driver side, because it only knows about 16K of the memory.
-   Anyone desperate or masochistic enough to try?
-
-   It seems to be stable now when multiple transmit buffers are used.  I
-   can't see any performance difference, but then I'm working on a 386SX.
-
-   Multicast doesn't work.  It doesn't even pretend to work.  Don't use
-   it.  Don't compile your kernel with multicast support.  I don't know
-   why.
-
-   Features:
-   This driver is useable as a loadable module.  If you try to specify an
-   IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
-   search the MCA slots until it finds a 3c523 with the specified
-   parameters.
-
-   This driver does support multiple ethernet cards when used as a module
-   (up to MAX_3C523_CARDS, the default being 4)
-
-   This has been tested with both BNC and TP versions, internal and
-   external transceivers.  Haven't tested with the 64K version (that I
-   know of).
-
-   History:
-   Jan 1st, 1996
-   first public release
-   Feb 4th, 1996
-   update to 1.3.59, incorporated multicast diffs from ni52.c
-   Feb 15th, 1996
-   added shared irq support
-   Apr 1999
-   added support for multiple cards when used as a module
-   added option to disable multicast as is causes problems
-       Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
-       Stuart Adamson <stuart.adamson@compsoc.net>
-   Nov 2001
-   added support for ethtool (jgarzik)

- *	My card accepts a buffer config of 4/4.
- *
- *	Setting the SAV BP bit does not save bad packets, but
- *	only enables RX on-card stats collection.
- *
- *	The documentation in places seems to miss things. In actual fact
- *	I've always eventually found everything is documented, it just
- *	requires careful study.
- *
- * DOC: Theory Of Operation
- *
- *	The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- *	amount of on board intelligence that housekeeps a somewhat dumber
- *	Intel NIC. For performance we want to keep the transmit queue deep
- *	as the card can transmit packets while fetching others from main
- *	memory by bus master DMA. Transmission and reception are driven by
- *	circular buffer queues.
- *
- *	The mailboxes can be used for controlling how the card traverses
- *	its buffer rings, but are used only for initial setup in this
- *	implementation.  The exec mailbox allows a variety of commands to
- *	be executed. Each command must complete before the next is
- *	executed. Primarily we use the exec mailbox for controlling the
- *	multicast lists.  We have to do a certain amount of interesting
- *	hoop jumping as the multicast list changes can occur in interrupt
- *	state when the card has an exec command pending. We defer such
- *	events until the command completion interrupt.
- *
- *	A copy break scheme (taken from 3c59x.c) is employed whereby
- *	received frames exceeding a configurable length are passed
- *	directly to the higher networking layers without incuring a copy,
- *	in what amounts to a time/space trade-off.
- *
- *	The card also keeps a large amount of statistical information
- *	on-board. In a perfect world, these could be used safely at no
- *	cost. However, lacking information to the contrary, processing
- *	them without races would involve so much extra complexity as to
- *	make it unworthwhile to do so. In the end, a hybrid SW/HW
- *	implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- *	It should be possible to use two or more cards, but at this stage
- *	only by loading two copies of the same module.
- *
- *	The on-board 82586 NIC has trouble receiving multiple
- *	back-to-back frames and so is likely to drop packets from fast
- *	senders.

+ * The 82580 timesync updates the system timer every 8ns by 8ns,
+ * and this update value cannot be reprogrammed.
+ *
+ * Neither the 82576 nor the 82580 offer registers wide enough to hold
+ * nanoseconds time values for very long. For the 82580, SYSTIM always
+ * counts nanoseconds, but the upper 24 bits are not availible. The
+ * frequency is adjusted by changing the 32 bit fractional nanoseconds
+ * register, TIMINCA.
+ *
+ * For the 82576, the SYSTIM register time unit is affect by the
+ * choice of the 24 bit TININCA:IV (incvalue) field. Five bits of this
+ * field are needed to provide the nominal 16 nanosecond period,
+ * leaving 19 bits for fractional nanoseconds.
+ *
+ * We scale the NIC clock cycle by a large factor so that relatively
+ * small clock corrections can be added or subtracted at each clock
+ * tick. The drawbacks of a large factor are a) that the clock
+ * register overflows more quickly (not such a big deal) and b) that
+ * the increment per tick has to fit into 24 bits.  As a result we
+ * need to use a shift of 19 so we can fit a value of 16 into the
+ * TIMINCA register.

+ * The 82599 and the X540 do not have true 64bit nanosecond scale
+ * counter registers. Instead, SYSTIME is defined by a fixed point
+ * system which allows the user to define the scale counter increment
+ * value at every level change of the oscillator driving the SYSTIME
+ * value. For both devices the TIMINCA:IV field defines this
+ * increment. On the X540 device, 31 bits are provided. However on the
+ * 82599 only provides 24 bits. The time unit is determined by the
+ * clock frequency of the oscillator in combination with the TIMINCA
+ * register. When these devices link at 10Gb the oscillator has a
+ * period of 6.4ns. In order to convert the scale counter into
+ * nanoseconds the cyclecounter and timecounter structures are
+ * used. The SYSTIME registers need to be converted to ns values by use
+ * of only a right shift (division by power of 2). The following math
+ * determines the largest incvalue that will fit into the available
+ * bits in the TIMINCA register.
+ *
+ * PeriodWidth: Number of bits to store the clock period
+ * MaxWidth: The maximum width value of the TIMINCA register
+ * Period: The clock period for the oscillator
+ * round(): discard the fractional portion of the calculation
+ *
+ * Period * [ 2 ^ ( MaxWidth - PeriodWidth ) ]
+ *
+ * For the X540, MaxWidth is 31 bits, and the base period is 6.4 ns
+ * For the 82599, MaxWidth is 24 bits, and the base period is 6.4 ns
+ *
+ * The period also changes based on the link speed:
+ * At 10Gb link or no link, the period remains the same.
+ * At 1Gb link, the period is multiplied by 10. (64ns)
+ * At 100Mb link, the period is multiplied by 100. (640ns)
+ *
+ * The calculated value allows us to right shift the SYSTIME register
+ * value in order to quickly convert it into a nanosecond clock,
+ * while allowing for the maximum possible adjustment value.
+ *
+ * These diagrams are only for the 10Gb link period

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- *   only one full element list is used.  This includes, for example,
- *   1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4.  (This
- *   is not an exhaustive list.)
- * - The RBUF uses 64-byte mpackets.
- * - RX descriptors reside in SRAM, and have the following format:
- *	struct rx_desc
- *	{
- *	// to uengine
- *		u32	buf_phys_addr;
- *		u32	buf_length;
- *
- *	// from uengine
- *		u32	channel;
- *		u32	pkt_length;
- *	};
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 0 is rx_pending.
- * - Scratch ring 1 is rx_done, and has status condition 'full'.
- * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
- * - This code is run on all eight threads of the microengine it runs on.
- *
- * Local memory is used for per-channel RX state.

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- *   only one TBUF partition is used.  This includes, for example,
- *   1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- *   is not an exhaustive list.)
- * - The TBUF uses 64-byte mpackets.
- * - TX descriptors reside in SRAM, and have the following format:
- *	struct tx_desc
- *	{
- *	// to uengine
- *		u32	buf_phys_addr;
- *		u32	pkt_length;
- *		u32	channel;
- *	};
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 2 is tx_pending.
- * - Scratch ring 3 is tx_done, and has status condition 'full'.
- * - This code is run on all eight threads of the microengine it runs on.

- *	Technical Card Details
- *
- *  All access to data is done with 16/8 bit transfers.  The transfer
- *  method really sucks. You can only read or write one location at a time.
- *
- *  Also, the microcode for the card must be uploaded if the card does not have
- *  the flashrom on board.  This is a 28K bloat in the driver when compiled
- *  as a module.
- *
- *  Rx is very simple, status into a ring of descriptors, dma data transfer,
- *  interrupts to tell us when a packet is received.
- *
- *  Tx is a little more interesting. Similar scenario, descriptor and dma data
- *  transfers, but we don't have to interrupt the card to tell it another packet
- *  is ready for transmission, we are just doing simple memory writes, not io or mmio
- *  writes.  The card can be set up to simply poll on the next
- *  descriptor pointer and when this value is non-zero will automatically download
- *  the next packet.  The card then interrupts us when the packet is done.

- *	There are two ways of implementing rx on the 359 NIC, either

- *	
- *	The Rx works with a ring of Rx descriptors.  At initialise time the ring
- *	entries point to the next entry except for the last entry in the ring 
- *	which points to 0.  The card is programmed with the location of the first
- *	available descriptor and keeps reading the next_ptr until next_ptr is set
- *	to 0.  Hopefully with a ring size of 16 the card will never get to read a next_ptr
- *	of 0.  As the Rx interrupt is received we copy the frame up to the protocol layers
- *	and then point the end of the ring to our current position and point our current
- *	position to 0, therefore making the current position the last position on the ring.
- *	The last position on the ring therefore loops continually loops around the rx ring.
- *	
- *	rx_ring_tail is the position on the ring to process next. (Think of a snake, the head 
- *	expands as the card adds new packets and we go around eating the tail processing the
- *	packets.)
- *
- *	Undoubtably it could be streamlined and improved upon, but at the moment it works 
- *	and the fast path through the routine is fine. 
- *	
- *	adv_rx_ring could be inlined to increase performance, but its called a *lot* of times
- *	in xl_rx so would increase the size of the function significantly.

- *		(Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- *	+ changed name to ibmtr.c in anticipation of other tr boards.
- *	+ changed reset code and adapter open code.
- *	+ added SAP open code.
- *	+ a first attempt to write interrupt, transmit and receive routines.
- *
- *	Changes by David W. Morris (dwm@shell.portal.com) :
- *	941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- *	+ Add comments, misc reorg for clarity.
- *	+ Flatten interrupt handler levels.
- *
- *	Changes by Farzad Farid (farzy@zen.via.ecp.fr)

- *	Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- *	+ bug correction in tr_tx
- *	+ removed redundant information display
- *	+ some code reworking
- *
- *	Changes by Michel Lespinasse (walken@via.ecp.fr),
- *	Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- *	(February 18, 1996) :
- *	+ modified shared memory and mmio access port the driver to
- *	  alpha platform (structure access -> readb/writeb)
- *
- *	Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- *	(January 18 1996):
- *	+ swapped WWOR and WWCR in ibmtr.h
- *	+ moved some init code from tok_probe into trdev_init.  The
- *	  PCMCIA code can call trdev_init to complete initializing
- *	  the driver.
- *	+ added -DPCMCIA to support PCMCIA
- *	+ detecting PCMCIA Card Removal in interrupt handler.  If
- *	  ISRP is FF, then a PCMCIA card has been removed
- *        10/2000 Burt needed a new method to avoid crashing the OS
- *
- *	Changes by Paul Norton (pnorton@cts.com) :
- *	+ restructured the READ.LOG logic to prevent the transmit SRB
- *	  from being rudely overwritten before the transmit cycle is
- *	  complete. (August 15 1996)
- *	+ completed multiple adapter support. (November 20 1996)
- *	+ implemented csum_partial_copy in tr_rx and increased receive 
- *        buffer size and count. Minor fixes. (March 15, 1997)
- *
- *	Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- *	+ Now compiles ok as a module again.
- *
- *	Changes by Paul Norton (pnorton@ieee.org) :
- *      + moved the header manipulation code in tr_tx and tr_rx to
- *        net/802/tr.c. (July 12 1997)
- *      + add retry and timeout on open if cable disconnected. (May 5 1998)
- *      + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- *        May 25 1998)
- *      + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- *      Changes by Joel Sloan (jjs@c-me.com) :
- *      + disable verbose debug messages by default - to enable verbose
- *	  debugging, edit the IBMTR_DEBUG_MESSAGES define below 
- *	
- *	Changes by Mike Phillips <phillim@amtrak.com> :
- *	+ Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- *	  The PCMCIA code now just sets up the card so it can be recognized
- *        by ibmtr_probe. Also checks allocated memory vs. on-board memory
- *	  for correct figure to use.
- *
- *	Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- *	+ added spinlocks for SMP sanity (10 March 1999)
- *
- *      Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- *      i.e. using functional address C0 00 00 04 00 00 to transmit and 
- *      receive multicast packets.
- *
- *      Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- *      to support windowing into on adapter shared ram.
- *      i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- *      will shift this 16K window over the entire available shared RAM.
- *
- *      Changes by Peter De Schrijver (p2@mind.be) :
- *      + fixed a problem with PCMCIA card removal
- *
- *      Change by Mike Sullivan et al.:
- *      + added turbo card support. No need to use lanaid to configure
- *      the adapter into isa compatibility mode.
- *
- *      Changes by Burt Silverman to allow the computer to behave nicely when
- *	a cable is pulled or not in place, or a PCMCIA card is removed hot.

-/*======================================================================
-
-    A PCMCIA token-ring driver for IBM-based cards
-
-    This driver supports the IBM PCMCIA Token-Ring Card.
-    Written by Steve Kipisz, kipisz@vnet.ibm.com or
-                             bungy@ibm.net
-
-    Written 1995,1996.
-
-    This code is based on pcnet_cs.c from David Hinds.
-    
-    V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
-    Linux V2.2.x presented significant changes to the underlying
-    ibmtr.c code.  Mainly the code became a lot more organized and
-    modular.
-
-    This caused the old PCMCIA Token Ring driver to give up and go 
-    home early. Instead of just patching the old code to make it 
-    work, the PCMCIA code has been streamlined, updated and possibly
-    improved.
-
-    This code now only contains code required for the Card Services.
-    All we do here is set the card up enough so that the real ibmtr.c
-    driver can find it and work with it properly.
-
-    i.e. We set up the io port, irq, mmio memory and shared ram
-    memory.  This enables ibmtr_probe in ibmtr.c to find the card and
-    configure it as though it was a normal ISA and/or PnP card.
-
-    CHANGES
-
-    v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
-    Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-    
-    v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
-    Updated to version 2.2.7 to match the first version of the kernel
-    that the modification to ibmtr.c were incorporated into.
-    
-    v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
-    Address translation feature of PCMCIA controller is usable so
-    memory windows can be placed in High memory (meaning above
-    0xFFFFF.)

- * 
- *  12/10/99 - Alpha Release 0.1.0
- *            First release to the public
- *  03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
- *		malloc free checks, reviewed code. <alan@redhat.com>
- *  03/13/00 - Added spinlocks for smp
- *  03/08/01 - Added support for module_init() and module_exit()
- *  08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
- *             calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
- *  11/05/01 - Restructured the interrupt function, added delays, reduced the 
- *             the number of TX descriptors to 1, which together can prevent 
- *             the card from locking up the box - <yoder1@us.ibm.com>
- *  09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
- *  11/13/02 - Removed free_irq calls which could cause a hang, added
- *	       netif_carrier_{on|off} - <yoder1@us.ibm.com>
- *  
- *  To Do:
- *
- *
- *  If Problems do Occur
- *  Most problems can be rectified by either closing and opening the interface
- *  (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- *  if compiled into the kernel).

-/*
- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed).  Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1)  	Read in the SIFSTS register from the TMS controller.  This
- *	is guaranteed to be accurate, however, there's a fairly
- *	large performance penalty for doing so: the Madge chips
- *	must request the register from the Eagle, the Eagle must
- *	read them from its internal bus, and then take the route
- *	back out again, for a 16bit read.  
- *
- * 2)	Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- *	The major disadvantage here is that the accuracy of the
- *	bit is in question.  However, it cuts out the extra read
- *	cycles it takes to read the Eagle's SIF, as its only an
- *	8bit read, and theoretically the Madge bit is directly
- *	connected to the interrupt latch coming out of the Eagle
- *	hardware (that statement is not verified).  
- *
- * I can't determine which of these methods has the best win.  For now,
- * we make a compromise.  Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first 
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.

- *
- *  6/8/99  - Official Release 0.2.0   
- *            Merged into the kernel code 
- *  8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- *	      resource. Driver also reports the card name returned by
- *            the pci resource.
- *  1/11/00 - Added spinlocks for smp
- *  2/23/00 - Updated to dev_kfree_irq 
- *  3/10/00 - Fixed FDX enable which triggered other bugs also 
- *            squashed.
- *  5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.

- *            endian issues with the big-endian data in the arb, asb...
- *            was to always swab() the bytes, no matter what CPU.
- *            That's because the read[wl]() functions always swap the

- *            Fixing the hardware descriptors was another matter,
- *            because they weren't going through read[wl](), there all
- *            the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up. 
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- *	      Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- *	      adapter when live does not take the system down with it.
- * 
- * 06/02/01 - Clean up, copy skb for small packets
- * 
- * 06/22/01 - Add EISR error handling routines 
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- *	      into a separate function, its called from 3 
- *	      different places now. 
- * 02/09/02 - Replaced sleep_on. 
- * 03/01/02 - Replace access to several registers from 32 bit to 
- * 	      16 bit. Fixes alignment errors on PPC 64 bit machines.
- * 	      Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * 	      silently ignored until the error checking code 
- * 	      went into version 1.0.0 
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * 	      Required for strict compliance with pci power mgmt specs.
- *  To Do:
- *
- *	     Wake on lan	
- * 
- *  If Problems do Occur
- *  Most problems can be rectified by either closing and opening the interface
- *  (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- *  if compiled into the kernel).

- *  skisa.c: A network driver for SK-NET TMS380-based ISA token ring cards.
- *
- *  Based on tmspci written 1999 by Adam Fritzler
- *  
- *  Written 2000 by Jochen Friedrich
- *  Dedicated to my girlfriend Steffi Bopp
- *
- *  This software may be used and distributed according to the terms
- *  of the GNU General Public License, incorporated herein by reference.
- *
- *  This driver module supports the following cards:
- *	- SysKonnect TR4/16(+) ISA	(SK-4190)
- *
- *  Maintainer(s):
- *    AF        Adam Fritzler
- *    JF	Jochen Friedrich	jochen@scram.de
- *
- *  Modification History:
- *	14-Jan-01	JF	Created
- *	28-Oct-02	JF	Fixed probe of card for static compilation.
- *				Fixed module init to not make hotplug go wild.
- *	09-Nov-02	JF	Fixed early bail out on out of memory
- *				situations if multiple cards are found.
- *				Cleaned up some unnecessary console SPAM.
- *	09-Dec-02	JF	Fixed module reference counting.
- *	02-Jan-03	JF	Renamed to skisa.c

-/*
- *  tms380tr.c: A network driver library for Texas Instruments TMS380-based
- *              Token Ring Adapters.
- *
- *  Originally sktr.c: Written 1997 by Christoph Goos
- *
- *  A fine result of the Linux Systems Network Architecture Project.
- *  http://www.vanheusden.com/sna/ 
- *
- *  This software may be used and distributed according to the terms
- *  of the GNU General Public License, incorporated herein by reference.
- *
- *  The following modules are currently available for card support:
- *	- tmspci (Generic PCI card support)
- *	- abyss (Madge PCI support)
- *      - tmsisa (SysKonnect TR4/16 ISA)
- *
- *  Sources:
- *  	- The hardware related parts of this driver are take from
- *  	  the SysKonnect Token Ring driver for Windows NT.
- *  	- I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- *  	  driver, as well as the 'skeleton.c' driver by Donald Becker.
- *  	- Also various other drivers in the linux source tree were taken
- *  	  as samples for some tasks.
- *      - TI TMS380 Second-Generation Token Ring User's Guide
- *  	- TI datasheets for respective chips
- *  	- David Hein at Texas Instruments 
- *  	- Various Madge employees
- *
- *  Maintainer(s):
- *    JS	Jay Schulist		jschlst@samba.org
- *    CG	Christoph Goos		cgoos@syskonnect.de
- *    AF	Adam Fritzler
- *    MLP       Mike Phillips           phillim@amtrak.com
- *    JF	Jochen Friedrich	jochen@scram.de
- *     
- *  Modification History:
- *	29-Aug-97	CG	Created
- *	04-Apr-98	CG	Fixed problems caused by tok_timer_check
- *	10-Apr-98	CG	Fixed lockups at cable disconnection
- *	27-May-98	JS	Formated to Linux Kernel Format
- *	31-May-98	JS	Hacked in PCI support
- *	16-Jun-98	JS	Modulized for multiple cards with one driver
- *	   Sep-99	AF	Renamed to tms380tr (supports more than SK's)
- *      23-Sep-99	AF      Added Compaq and Thomas-Conrad PCI support
- *				Fixed a bug causing double copies on PCI
- *				Fixed for new multicast stuff (2.2/2.3)
- *	25-Sep-99	AF	Uped TPL_NUM from 3 to 9
- *				Removed extraneous 'No free TPL'
- *	22-Dec-99	AF	Added Madge PCI Mk2 support and generalized
- *				parts of the initilization procedure.
- *	30-Dec-99	AF	Turned tms380tr into a library ala 8390.
- *				Madge support is provided in the abyss module
- *				Generic PCI support is in the tmspci module.
- *	30-Nov-00	JF	Updated PCI code to support IO MMU via
- *				pci_map_static(). Alpha uses this MMU for ISA
- *				as well.
- *      14-Jan-01	JF	Fix DMA on ifdown/ifup sequences. Some 
- *      			cleanup.
- *	13-Jan-02	JF	Add spinlock to fix race condition.
- *	09-Nov-02	JF	Fixed printks to not SPAM the console during
- *				normal operation.
- *	30-Dec-02	JF	Removed incorrect __init from 
- *				tms380tr_init_card.
- *	22-Jul-05	JF	Converted to dma-mapping.
- *      			
- *  To do:
- *    1. Multi/Broadcast packet handling (this may have fixed itself)
- *    2. Write a sktrisa module that includes the old ISA support (done)
- *    3. Allow modules to load their own microcode
- *    4. Speed up the BUD process -- freezing the kernel for 3+sec is
- *         quite unacceptable.
- *    5. Still a few remaining stalls when the cable is unplugged.

- * DOC: shared area - role and goal
- *
- * The shared area contains all the data exported by the upper layer to the
- * other layers. Since the bus and transport layer shouldn't dereference
- * iwl_priv, all the data needed by the upper layer and the transport / bus
- * layer must be here.
- * The shared area also holds pointer to all the other layers. This allows a
- * layer to call a function from another layer.
- *
- * NOTE: All the layers hold a pointer to the shared area which must be shrd.
- *	A few macros assume that (_m)->shrd points to the shared area no matter
- *	what _m is.
- *
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c
