+ *	  And still doesn't work on Intel card. Grrrr...
+ *	o Update the mode after a setport3
+ *	o Add preamble setting for Symbol cards (not yet enabled)
+ *	o Don't complain as much about Symbol cards...

+ *	o Remove deferred power enabling code
+ *
+ * v0.05c -> v0.05d - 5/5/2001 - Jean II
+ *	o Workaround to SNAP decapsulate frame from LinkSys AP
+ *	  original patch from : Dong Liu <dliu@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@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 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 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. */
+
+/* Locking and synchronization:
+ *
+ * The basic principle is that everything is serialized through a
+ * single spinlock, priv->lock.  The lock is used in user, bh and irq
+ * context, so when taken outside hardirq context it should always be
+ * taken with interrupts disabled.  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).  This flag is protected by the
+ * spinlock.  All code which touches the hardware should check the
+ * flag after taking the lock, and if it is set, give up on whatever
+ * they are doing and drop the lock again.  The orinoco_lock()
+ * function handles this (it unlocks and returns -EBUSY if
+ * hw_unavailable is non-zero). */
