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.
