- *
- * v0.05d -> v0.06 - 25/5/2001 - Jean II
- * Original patch from "Hong Lin" <alin@redhat.com>,
- * "Ian Kinner" <ikinner@redhat.com>
- * and "David Smith" <dsmith@redhat.com>
- * o Init of priv->tx_rate_ctrl in firmware specific section.

- * o IBSS on Symbol use port_mode = 4. Please don't ask...
- *
- * v0.06b -> v0.06c - 29/5/2001 - Jean II

- *
- * v0.06c -> v0.06d - 6/7/2001 - David Gibson

- * wishes to reduce the number of unecessary messages.
- * o Removed bogus message on CRC error.
- * o Merged fixeds for v0.08 Prism 2 firmware from William Waghorn
- * <willwaghorn@yahoo.co.uk>
- * o Slight cleanup/re-arrangement of firmware detection code.
- *
- * v0.06d -> v0.06e - 1/8/2001 - David Gibson
- * o Removed some redundant global initializers (orinoco_cs.c).
- * o Added some module metadataa
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson
- * o Wording fix to license
- * o Added a 'use_alternate_encaps' module parameter for APs which need an
- * oui of 00:00:00. 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@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
- * realised 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 brdge) cards.
- * o Changed to using the new type-facist 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 normalisation of signel 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 cofusing 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.
- *
* 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. */
