We really need a better way of handling this, but + * the module flag is better than nothing for now. + * + * v0.06f -> v0.07 - 20/8/2001 - David Gibson + * o Removed BAP error retries from hermes_bap_seek(). For Tx we now + * let the upper layers handle the retry, we retry explicitly in the + * Rx path, but don't make as much noise about it. + * o Firmware detection cleanups. + * + * v0.07 -> v0.07a - 1/10/3001 - Jean II + * o Add code to read Symbol firmware revision, inspired by latest code + * in Spectrum24 by Lee John Keyser-Allen - Thanks Lee ! + * o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me + * a 3Com card with a recent firmware, fill out Symbol firmware + * capabilities of latest rev (2.20), as well as older Symbol cards. + * o Disable Power Management in newer Symbol firmware, the API + * has changed (documentation needed). + * + * v0.07a -> v0.08 - 3/10/2001 - David Gibson + * o Fixed a possible buffer overrun found by the Stanford checker (in + * dldwd_ioctl_setiwencode()). Can only be called by root anyway, so not + * a big problem. + * o Turned has_big_wep on for Intersil cards. That's not true for all of + * them but we should at least let the capable ones try. + * o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I + * realized that my assumption that the driver's serialization + * would prevent the BAP being busy on entry was possibly false, because + * things other than seeks may make the BAP busy. + * o Use "alternate" (oui 00:00:00) encapsulation by default. + * Setting use_old_encaps will mimic the old behaviour, but I think we + * will be able to eliminate this. + * o Don't try to make __initdata const (the version string). This can't + * work because of the way the __initdata sectioning works. + * o Added MODULE_LICENSE tags. + * o Support for PLX (transparent PCMCIA->PCI bridge) cards. + * o Changed to using the new type-fascist min/max. + * + * v0.08 -> v0.08a - 9/10/2001 - David Gibson + * o Inserted some missing acknowledgements/info into the Changelog. + * o Fixed some bugs in the normalization of signal level reporting. + * o Fixed bad bug in WEP key handling on Intersil and Symbol firmware, + * which led to an instant crash on big-endian machines. + * + * v0.08a -> v0.08b - 20/11/2001 - David Gibson + * o Lots of cleanup and bugfixes in orinoco_plx.c + * o Cleanup to handling of Tx rate setting. + * o Removed support for old encapsulation method. + * o Removed old "dldwd" names. + * o Split RID constants into a new file hermes_rid.h + * o Renamed RID constants to match linux-wlan-ng and prism2.o + * o Bugfixes in hermes.c + * o Poke the PLX's INTCSR register, so it actually starts + * generating interrupts. These cards might actually work now. + * o Update to wireless extensions v12 (Jean II) + * o Support for tallies and inquire command (Jean II) + * o Airport updates for newer PPC kernels (BenH) + * + * v0.08b -> v0.09 - 21/12/2001 - David Gibson + * o Some new PCI IDs for PLX cards. + * o Removed broken attempt to do ALLMULTI reception. Just use + * promiscuous mode instead + * o Preliminary work for list-AP (Jean II) + * o Airport updates from (BenH) + * o Eliminated racy hw_ready stuff + * o Fixed generation of fake events in irq handler. This should + * finally kill the EIO problems (Jean II & dgibson) + * o Fixed breakage of bitrate set/get on Agere firmware (Jean II) + * + * v0.09 -> v0.09a - 2/1/2002 - David Gibson + * o Fixed stupid mistake in multicast list handling, triggering + * a BUG() + * + * v0.09a -> v0.09b - 16/1/2002 - David Gibson + * o Fixed even stupider mistake in new interrupt handling, which + * seriously broke things on big-endian machines. + * o Removed a bunch of redundant includes and exports. + * o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c + * o Don't attempt to do hardware level multicast reception on + * Intersil firmware, just go promisc instead. + * o Typo fixed in hermes_issue_cmd() + * o Eliminated WIRELESS_SPY #ifdefs + * o Status code reported on Tx exceptions + * o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC + * interrupts, which should fix the timeouts we're seeing. + * + * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson + * o Removed nested structures used for header parsing, so the + * driver should now work without hackery on ARM + * o Fix for WEP handling on Intersil (Hawk Newton) + * o Eliminated the /proc/hermes/ethXX/regs debugging file. It + * was never very useful. + * o Make Rx errors less noisy. + * + * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson + * o Laid the groundwork in hermes.[ch] for devices which map + * into PCI memory space rather than IO space. + * o Fixed bug in multicast handling (cleared multicast list when + * leaving promiscuous mode). + * o Relegated Tx error messages to debug. + * o Cleaned up / corrected handling of allocation lengths. + * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc). + * o Change to using alloc_etherdev() for structure allocations. + * o Check for and drop undersized packets. + * o Fixed a race in stopping/waking the queue. This should fix + * the timeout problems (Pavel Roskin) + * o Reverted to netif_wake_queue() on the ALLOC event. + * o Fixes for recent Symbol firmwares which lack AP density + * (Pavel Roskin). + * + * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson + * o Handle different register spacing, necessary for Prism 2.5 + * PCI adaptors (Steve Hill). + * o Cleaned up initialization of card structures in orinoco_cs + * and airport. Removed card->priv field. + * o Make response structure optional for hermes_docmd_wait() + * Pavel Roskin) + * o Added PCI id for Nortel emobility to orinoco_plx.c. + * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin) + * o Cleanups to firmware capability detection. + * o Arrange for orinoco_pci.c to override firmware detection. + * We should be able to support the PCI Intersil cards now. + * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin). + * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni + * Malinen). + * o Makefile changes for better integration into David Hinds + * pcmcia-cs package. + * + * v0.11a -> v0.11b - 1 May 2002 - David Gibson + * o Better error reporting in orinoco_plx_init_one() + * o Fixed multiple bad kfree() bugs introduced by the + * alloc_orinocodev() changes. + * + * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson + * o Support changing the MAC address. + * o Correct display of Intersil firmware revision numbers. + * o Entirely revised locking scheme. Should be both simpler and + * better. + * o Merged some common code in orinoco_plx, orinoco_pci and + * airport by creating orinoco_default_{open,stop,reset}() + * which are used as the dev->open, dev->stop, priv->reset + * callbacks if none are specified when alloc_orinocodev() is + * called. + * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt(). + * They didn't do anything. + * + * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson + * o Some rearrangement of code. + * o Numerous fixups to locking and rest handling, particularly + * for PCMCIA. + * o This allows open and stop net_device methods to be in + * orinoco.c now, rather than in the init modules. + * o In orinoco_cs.c link->priv now points to the struct + * net_device not to the struct orinoco_private. + * o Added a check for undersized SNAP frames, which could cause + * crashes. + * + * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson + * o Fix hw->num_init testing code, so num_init is actually + * incremented. + * o Fix very stupid bug in orinoco_cs which broke compile with + * CONFIG_SMP. + * o Squashed a warning. + * + * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson + * o Change to C9X style designated initializers. + * o Add support for 3Com AirConnect PCI. + * o No longer ignore the hard_reset argument to + * alloc_orinocodev(). Oops. + * + * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson + * o Revert the broken 0.12* locking scheme and go to a new yet + * simpler scheme. + * o Do firmware resets only in orinoco_init() and when waking + * the card from hard sleep. + * + * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson + * o Re-introduced full resets (via schedule_task()) on Tx + * timeout. + * + * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson + * o Minor cleanups to info frame handling. Add basic support + * for linkstatus info frames. + * o Include required kernel headers in orinoco.h, to avoid + * compile problems. + * + * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson + * o Implemented hard reset for Airport cards + * o Experimental suspend/resume implementation for orinoco_pci + * o Abolished /proc debugging support, replaced with a debugging + * iwpriv. Now it's ugly and simple instead of ugly and complex. + * o Bugfix in hermes.c if the firmware returned a record length + * of 0, we could go clobbering memory. + * o Bugfix in orinoco_stop() - it used to fail if hw_unavailable + * was set, which was usually true on PCMCIA hot removes. + * o Track LINKSTATUS messages, silently drop Tx packets before + * we are connected (avoids confusing the firmware), and only + * give LINKSTATUS printk()s if the status has changed. + * + * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson + * o Cleanup: use dev instead of priv in various places. + * o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event + * if we're in the middle of a (driver initiated) hard reset. + * o Bug fix: ETH_ZLEN is supposed to include the header + * (Dionysus Blazakis & Manish Karir) + * o Convert to using workqueues instead of taskqueues (and + * backwards compatibility macros for pre 2.5.41 kernels). + * o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in + * airport.c + * o New orinoco_tmd.c init module from Joerg Dorchain for + * TMD7160 based PCI to PCMCIA bridges (similar to + * orinoco_plx.c). + * + * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson + * o Make hw_unavailable a counter, rather than just a flag, this + * is necessary to avoid some races (such as a card being + * removed in the middle of orinoco_reset(). + * o Restore Release/RequestConfiguration in the PCMCIA event handler + * when dealing with a driver initiated hard reset. This is + * necessary to prevent hangs due to a spurious interrupt while + * the reset is in progress. + * o Clear the 802.11 header when transmitting, even though we + * don't use it. This fixes a long standing bug on some + * firmwares, which seem to get confused if that isn't done. + * o Be less eager to de-encapsulate SNAP frames, only do so if + * the OUI is 00:00:00 or 00:00:f8, leave others alone. The old + * behaviour broke CDP (Cisco Discovery Protocol). + * o Use dev instead of priv for free_irq() as well as + * request_irq() (oops). + * o Attempt to reset rather than giving up if we get too many + * IRQs. + * o Changed semantics of __orinoco_down() so it can be called + * safely with hw_unavailable set. It also now clears the + * linkstatus (since we're going to have to reassociate). + * + * v0.13d -> v0.13e - 12 May 2003 - David Gibson + * o Support for post-2.5.68 return values from irq handler. + * o Fixed bug where underlength packets would be double counted + * in the rx_dropped statistics. + * o Provided a module parameter to suppress linkstatus messages. + * + * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson + * o Replaced priv->connected logic with netif_carrier_on/off() + * calls. + * o Remove has_ibss_any and never set the CREATEIBSS RID when + * the ESSID is empty. Too many firmwares break if we do. + * o 2.6 merges: Replace pdev->slot_name with pci_name(), remove + * __devinitdata from PCI ID tables, use free_netdev(). + * o Enabled shared-key authentication for Agere firmware (from + * Robert J. Moore <Robert.J.Moore AT allanbank.com> + * o Move netif_wake_queue() (back) to the Tx completion from the + * ALLOC event. This seems to prevent/mitigate the rolling + * error -110 problems at least on some Intersil firmwares. + * Theoretically reduces performance, but I can't measure it. + * Patch from Andrew Tridgell <tridge AT samba.org> + * + * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson + * o Correctly turn off shared-key authentication when requested + * (bugfix from Robert J. Moore). + * o Correct airport sleep interfaces for current 2.6 kernels. + * o Add code for key change without disabling/enabling the MAC + * port. This is supposed to allow 802.1x to work sanely, but + * doesn't seem to yet. + * + * TODO + * o New wireless extensions API (patch from Moustafa + * Youssef, updated by Jim Carter and Pavel Roskin). + * o Handle de-encapsulation within network layer, provide 802.11 + * headers (patch from Thomas 'Dent' Mirlacher) + * o RF monitor mode support + * o Fix possible races in SPY handling. + * o Disconnect wireless extensions from fundamental configuration. + * o (maybe) Software WEP support (patch from Stano Meduna). + * o (maybe) Use multiple Tx buffers - driver handling queue + * rather than firmware. + */ + +/* Locking and synchronization: + * + * The basic principle is that everything is serialized through a + * single spinlock, priv->lock.

The lock protects both the + * hardware and the struct orinoco_private. + * + * Another flag, priv->hw_unavailable indicates that the hardware is + * unavailable for an extended period of time (e.g. suspended, or in + * the middle of a hard reset).
