* o Fix Prism2/Symbol WEP to accept 128 bits keys
* o Add Symbol WEP (add authentication type)
* o Add Prism2/Symbol rate
* o Add PM timeout (holdover duration)
* o Enable "iwconfig eth0 key off" and friends (toggle flags)
* o Enable "iwconfig eth0 power unicast/all" (toggle flags)

* an antiquated firmware, however on windows it says 2.00. Yuck !
* o Workaround firmware bug in allocate buffer (Intel 1.01)
* o Finish external renaming to orinoco...
* o Testing with various Wavelan firmwares
*
* v0.03 -> v0.04 - 30/3/2001 - Jean II

* o Tested with a D-Link DWL 650 card, fill in firmware support
* o Warning on Vcc mismatch (D-Link 3.3v card in Lucent 5v only slot)
* o Fixed the Prism2 WEP bugs that I introduced in v0.03 :-(
* It works on D-Link *only* after a tcpdump. Weird...
* 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...
*
* v0.04 -> v0.04b - 22/4/2001 - David Gibson
* o Removed the 'eth' parameter - always use ethXX as the
* interface name instead of dldwdXX. The other was racy
* anyway.

*
* v0.05a -> v0.05b - 4/5/2001 - Jean II
* o add module parameter 'ignore_cis_vcc' for D-Link @ 5V
* o D-Link firmware doesn't support multicast. We just print a few
* error messages, but otherwise everything works...
* o For David : set/getport3 works fine, just upgrade iwpriv...
*
* v0.05b -> v0.05c - 5/5/2001 - Benjamin Herrenschmidt
* o Adapt airport.c to latest changes in orinoco.c
* 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 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 Prism2/Symbol rate, upto should be 0xF and not 0x15. Doh !
* o Spectrum card always need cor_reset (for every reset)
* o Fix cor_reset to not lose bit 7 in the register
* o flush_stale_links to remove zombie Pcmcia instances
* o Ack previous hermes event before reset
* Me (with my little hands)
* o Allow orinoco.c to call cor_reset via priv->card_reset_handler
* 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).
