- *	o Update the mode after a setport3
- *	o Add preamble setting for Symbol cards (not yet enabled)

- *	o Workaround to SNAP decapsulate frame from Linksys AP
- *	  original patch from : Dong Liu <dliu AT research.bell-labs.com>
- *	  (note : the memcmp bug was mine - fixed)
- *	o Remove set_retry stuff, no firmware support it (bloat--).
- *
- * v0.05d -> v0.06 - 25/5/2001 - Jean II
- *		Original patch from "Hong Lin" <alin AT redhat.com>,
- *		"Ian Kinner" <ikinner AT redhat.com>
- *		and "David Smith" <dsmith AT redhat.com>
- *	o Init of priv->tx_rate_ctrl in firmware specific section.

- *	o Add priv->need_card_reset to toggle this feature
- *	o Fix various buglets when setting WEP in Symbol firmware
- *	  Now, encryption is fully functional on Symbol cards. Youpi !
- *
- * v0.06 -> v0.06b - 25/5/2001 - Jean II
- *	o IBSS on Symbol use port_mode = 4. Please don't ask...
- *
- * v0.06b -> v0.06c - 29/5/2001 - Jean II
- *	o Show first spy address in /proc/net/wireless for IBSS mode as well
- *
- * v0.06c -> v0.06d - 6/7/2001 - David Gibson
- *      o Change a bunch of KERN_INFO messages to KERN_DEBUG, as per Linus'
- *        wishes to reduce the number of unnecessary messages.
- *	o Removed bogus message on CRC error.
- *	o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
- *	  <willwaghorn AT 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 metadata
- *
- * 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 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).
