+/* at1700.c: A network device driver for the Allied Telesis AT1700.

+ Director, National Security Agency.

+
+ This is a device driver for the Allied Telesis AT1700, and
+ Fujitsu FMV-181/182/181A/182A/183/184/183A/184A, which are
+ straight-forward Fujitsu MB86965 implementations.
+
+ Modification for Fujitsu FMV-18X cards is done by Yutaka Tamiya
+ (tamy@flab.fujitsu.co.jp).
+
+ Sources:
+ The Fujitsu MB86965 datasheet.
+
+ After the initial version of this driver was written Gerry Sawkins of
+ ATI provided their EEPROM configuration code header file.
+ Thanks to NIIBE Yutaka <gniibe@mri.co.jp> for bug fixes.
+
+ MCA bus (AT1720) support by Rene Schmit <rene@bss.lu>
+
+ Bugs:
+ The MB86965 has a design flaw that makes all probes unreliable. Not
+ only is it difficult to detect, it also moves around in I/O space in
+ response to inb()s from other device probes!

+
+ Written 1994-1999 by Mika Kuoppala

+ Copyright (C) 1994-1999 by Mika Kuoppala
+ Based on skeleton.c and heavily on at1700.c by Donald Becker
+
+ This software may be used and distributed according to the terms
+ of the GNU General Public License, incorporated herein by reference.
+
+ The author may be reached as miku@iki.fi
+
+ This driver supports following cards :
+ - ICL EtherTeam 16i
+ - ICL EtherTeam 32 EISA
+ (Uses true 32 bit transfers rather than 16i compatibility mode)
+
+ Example Module usage:
+ insmod eth16i.o io=0x2a0 mediatype=bnc
+
+ mediatype can be one of the following: bnc,tp,dix,auto,eprom
+
+ 'auto' will try to autoprobe mediatype.
+ 'eprom' will use whatever type defined in eprom.
+
+ I have benchmarked driver with PII/300Mhz as a ftp client
+ and 486/33Mhz as a ftp server. Top speed was 1128.37 kilobytes/sec.

+
+ Revision history:
+
+ Version Date Description
+
+ 0.01 15.12-94 Initial version (card detection)
+ 0.02 23.01-95 Interrupt is now hooked correctly
+ 0.03 01.02-95 Rewrote initialization part
+ 0.04 07.02-95 Base skeleton done...
+ Made a few changes to signature checking
+ to make it a bit reliable.
+ - fixed bug in tx_buf mapping
+ - fixed bug in initialization (DLC_EN
+ wasn't enabled when initialization
+ was done.)
+ 0.05 08.02-95 If there were more than one packet to send,
+ transmit was jammed due to invalid
+ register write...now fixed
+ 0.06 19.02-95 Rewrote interrupt handling
+ 0.07 13.04-95 Wrote EEPROM read routines
+ Card configuration now set according to
+ data read from EEPROM
+ 0.08 23.06-95 Wrote part that tries to probe used interface
+ port if AUTO is selected
+
+ 0.09 01.09-95 Added module support
+
+ 0.10 04.09-95 Fixed receive packet allocation to work
+ with kernels > 1.3.x
+
+ 0.20 20.09-95 Added support for EtherTeam32 EISA
+
+ 0.21 17.10-95 Removed the unnecessary extern
+ init_etherdev() declaration. Some
+ other cleanups.
+
+ 0.22 22.02-96 Receive buffer was not flushed
+ correctly when faulty packet was
+ received. Now fixed.
+
+ 0.23 26.02-96 Made resetting the adapter
+ more reliable.
+
+ 0.24 27.02-96 Rewrote faulty packet handling in eth16i_rx
+
+ 0.25 22.05-96 kfree() was missing from cleanup_module.
+
+ 0.26 11.06-96 Sometimes card was not found by
+ check_signature(). Now made more reliable.
+
+ 0.27 23.06-96 Oops. 16 consecutive collisions halted
+ adapter. Now will try to retransmit
+ MAX_COL_16 times before finally giving up.
+
+ 0.28 28.10-97 Added dev_id parameter (NULL) for free_irq
+
+ 0.29 29.10-97 Multiple card support for module users
+
+ 0.30 30.10-97 Fixed irq allocation bug.
+ (request_irq moved from probe to open)
+
+ 0.30a 21.08-98 Card detection made more relaxed. Driver
+ had problems with some TCP/IP-PROM boots
+ to find the card. Suggested by
+ Kurt Huwig <kurt@huwig.de>
+
+ 0.31 28.08-98 Media interface port can now be selected
+ with module parameters or kernel
+ boot parameters.
+
+ 0.32 31.08-98 IRQ was never freed if open/close
+ pair wasn't called. Now fixed.
+
+ 0.33 10.09-98 When eth16i_open() was called after
+ eth16i_close() chip never recovered.
+ Now more shallow reset is made on
+ close.
+
+ 0.34 29.06-99 Fixed one bad #ifdef.
+ Changed ioaddr -> io for consistency
+
+ 0.35 01.07-99 transmit,-receive bytes were never
+ updated in stats.
+
+ Bugs:
+ In some cases the media interface autoprobing code doesn't find
+ the correct interface type. In this case you can
+ manually choose the interface type in DOS with E16IC.EXE which is
+ configuration software for EtherTeam16i and EtherTeam32 cards.
+ This is also true for IRQ setting. You cannot use module
+ parameter to configure IRQ of the card (yet).
+
+ To do:
+ - Real multicast support
+ - Rewrite the media interface autoprobing code. Its _horrible_ !
+ - Possibly merge all the MB86965 specific code to external
+ module for use by eth16.c and Donald's at1700.c
+ - IRQ configuration with module parameter. I will do
+ this when i will get enough info about setting
+ irq without configuration utility.
