Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * 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 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).
+ * 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).
