115  *        original patch from : Dong Liu <dliu AT research.bell-labs.com>
116  *        (note : the memcmp bug was mine - fixed)
117  *      o Remove set_retry stuff, no firmware support it (bloat--).
118  *
119  * v0.05d -> v0.06 - 25/5/2001 - Jean II

139  *      o Show first spy address in /proc/net/wireless for IBSS mode as well
140  *
141  * v0.06c -> v0.06d - 6/7/2001 - David Gibson
142  *      o Change a bunch of KERN_INFO messages to KERN_DEBUG, as per Linus'

151  *      o Added some module metadata
152  *
153  * v0.06e -> v0.06f - 14/8/2001 - David Gibson
154  *      o Wording fix to license
155  *      o Added a 'use_alternate_encaps' module parameter for APs which need an
156  *        oui of 00:00:00.  We really need a better way of handling this, but
157  *        the module flag is better than nothing for now.
158  *
159  * v0.06f -> v0.07 - 20/8/2001 - David Gibson
160  *      o Removed BAP error retries from hermes_bap_seek().  For Tx we now
161  *        let the upper layers handle the retry, we retry explicitly in the
162  *        Rx path, but don't make as much noise about it.
163  *      o Firmware detection cleanups.
164  *
165  * v0.07 -> v0.07a - 1/10/3001 - Jean II
166  *      o Add code to read Symbol firmware revision, inspired by latest code
167  *        in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
168  *      o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
169  *        a 3Com card with a recent firmware, fill out Symbol firmware
170  *        capabilities of latest rev (2.20), as well as older Symbol cards.
171  *      o Disable Power Management in newer Symbol firmware, the API 
172  *        has changed (documentation needed).
173  *
174  * v0.07a -> v0.08 - 3/10/2001 - David Gibson
175  *      o Fixed a possible buffer overrun found by the Stanford checker (in
176  *        dldwd_ioctl_setiwencode()).  Can only be called by root anyway, so not
177  *        a big problem.
178  *      o Turned has_big_wep on for Intersil cards.  That's not true for all of
179  *        them but we should at least let the capable ones try.
180  *      o Wait for BUSY to clear at the beginning of hermes_bap_seek().  I
181  *        realized that my assumption that the driver's serialization
182  *        would prevent the BAP being busy on entry was possibly false, because
183  *        things other than seeks may make the BAP busy.
184  *      o Use "alternate" (oui 00:00:00) encapsulation by default.
185  *        Setting use_old_encaps will mimic the old behaviour, but I think we
186  *        will be able to eliminate this.
187  *      o Don't try to make __initdata const (the version string).  This can't
188  *        work because of the way the __initdata sectioning works.
189  *      o Added MODULE_LICENSE tags.
190  *      o Support for PLX (transparent PCMCIA->PCI bridge) cards.
191  *      o Changed to using the new type-fascist min/max.
192  *
193  * v0.08 -> v0.08a - 9/10/2001 - David Gibson
194  *      o Inserted some missing acknowledgements/info into the Changelog.
195  *      o Fixed some bugs in the normalization of signal level reporting.
196  *      o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
197  *        which led to an instant crash on big-endian machines.
198  *
199  * v0.08a -> v0.08b - 20/11/2001 - David Gibson
200  *      o Lots of cleanup and bugfixes in orinoco_plx.c
201  *      o Cleanup to handling of Tx rate setting.
202  *      o Removed support for old encapsulation method.
203  *      o Removed old "dldwd" names.
204  *      o Split RID constants into a new file hermes_rid.h
205  *      o Renamed RID constants to match linux-wlan-ng and prism2.o
206  *      o Bugfixes in hermes.c
207  *      o Poke the PLX's INTCSR register, so it actually starts
208  *        generating interrupts.  These cards might actually work now.
209  *      o Update to wireless extensions v12 (Jean II)
210  *      o Support for tallies and inquire command (Jean II)
211  *      o Airport updates for newer PPC kernels (BenH)
212  *
213  * v0.08b -> v0.09 - 21/12/2001 - David Gibson
214  *      o Some new PCI IDs for PLX cards.
215  *      o Removed broken attempt to do ALLMULTI reception.  Just use
216  *        promiscuous mode instead
217  *      o Preliminary work for list-AP (Jean II)
218  *      o Airport updates from (BenH)
219  *      o Eliminated racy hw_ready stuff
220  *      o Fixed generation of fake events in irq handler.  This should
221  *        finally kill the EIO problems (Jean II & dgibson)
222  *      o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
223  *
224  * v0.09 -> v0.09a - 2/1/2002 - David Gibson
225  *      o Fixed stupid mistake in multicast list handling, triggering
226  *        a BUG()
227  *
228  * v0.09a -> v0.09b - 16/1/2002 - David Gibson
229  *      o Fixed even stupider mistake in new interrupt handling, which
230  *        seriously broke things on big-endian machines.
231  *      o Removed a bunch of redundant includes and exports.
232  *      o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
233  *      o Don't attempt to do hardware level multicast reception on
234  *        Intersil firmware, just go promisc instead.
235  *      o Typo fixed in hermes_issue_cmd()
236  *      o Eliminated WIRELESS_SPY #ifdefs
237  *      o Status code reported on Tx exceptions
238  *      o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
239  *        interrupts, which should fix the timeouts we're seeing.
240  *
241  * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
242  *      o Removed nested structures used for header parsing, so the

244  *      o Fix for WEP handling on Intersil (Hawk Newton)
245  *      o Eliminated the /proc/hermes/ethXX/regs debugging file.  It
246  *        was never very useful.
247  *      o Make Rx errors less noisy.
248  *
249  * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
250  *      o Laid the groundwork in hermes.[ch] for devices which map
251  *        into PCI memory space rather than IO space.
252  *      o Fixed bug in multicast handling (cleared multicast list when
253  *        leaving promiscuous mode).

293  *      o Merged some common code in orinoco_plx, orinoco_pci and
294  *        airport by creating orinoco_default_{open,stop,reset}()
295  *        which are used as the dev->open, dev->stop, priv->reset
296  *        callbacks if none are specified when alloc_orinocodev() is
297  *        called.
298  *      o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
299  *        They didn't do anything.
300  *
301  * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
302  *      o Some rearrangement of code.
303  *      o Numerous fixups to locking and rest handling, particularly
304  *        for PCMCIA.
305  *      o This allows open and stop net_device methods to be in
306  *        orinoco.c now, rather than in the init modules.
307  *      o In orinoco_cs.c link->priv now points to the struct
308  *        net_device not to the struct orinoco_private.
309  *      o Added a check for undersized SNAP frames, which could cause
310  *        crashes.
311  *
312  * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
313  *      o Fix hw->num_init testing code, so num_init is actually
314  *        incremented.
315  *      o Fix very stupid bug in orinoco_cs which broke compile with
316  *        CONFIG_SMP.
317  *      o Squashed a warning.
318  *
319  * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
320  *      o Change to C9X style designated initializers.
321  *      o Add support for 3Com AirConnect PCI.
322  *      o No longer ignore the hard_reset argument to
323  *        alloc_orinocodev().  Oops.
324  *
325  * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
326  *      o Revert the broken 0.12* locking scheme and go to a new yet
327  *        simpler scheme.
328  *      o Do firmware resets only in orinoco_init() and when waking
329  *        the card from hard sleep.
330  *
331  * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
332  *      o Re-introduced full resets (via schedule_task()) on Tx
333  *        timeout.
334  *
335  * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
336  *      o Minor cleanups to info frame handling.  Add basic support
337  *        for linkstatus info frames.
338  *      o Include required kernel headers in orinoco.h, to avoid
339  *        compile problems.
340  *
341  * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
342  *      o Implemented hard reset for Airport cards
343  *      o Experimental suspend/resume implementation for orinoco_pci
344  *      o Abolished /proc debugging support, replaced with a debugging
345  *        iwpriv.  Now it's ugly and simple instead of ugly and complex.
346  *      o Bugfix in hermes.c if the firmware returned a record length
347  *        of 0, we could go clobbering memory.
348  *      o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
349  *        was set, which was usually true on PCMCIA hot removes.
350  *      o Track LINKSTATUS messages, silently drop Tx packets before
351  *        we are connected (avoids confusing the firmware), and only
352  *        give LINKSTATUS printk()s if the status has changed.
353  *
354  * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
355  *      o Cleanup: use dev instead of priv in various places.
356  *      o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
357  *        if we're in the middle of a (driver initiated) hard reset.
358  *      o Bug fix: ETH_ZLEN is supposed to include the header
359  *        (Dionysus Blazakis & Manish Karir)
360  *      o Convert to using workqueues instead of taskqueues (and
361  *        backwards compatibility macros for pre 2.5.41 kernels).
362  *      o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
363  *        airport.c
364  *      o New orinoco_tmd.c init module from Joerg Dorchain for
365  *        TMD7160 based PCI to PCMCIA bridges (similar to
366  *        orinoco_plx.c).
367  *
368  * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
369  *      o Make hw_unavailable a counter, rather than just a flag, this
370  *        is necessary to avoid some races (such as a card being
371  *        removed in the middle of orinoco_reset().
372  *      o Restore Release/RequestConfiguration in the PCMCIA event handler
373  *        when dealing with a driver initiated hard reset.  This is
374  *        necessary to prevent hangs due to a spurious interrupt while
375  *        the reset is in progress.
376  *      o Clear the 802.11 header when transmitting, even though we
377  *        don't use it.  This fixes a long standing bug on some
378  *        firmwares, which seem to get confused if that isn't done.
379  *      o Be less eager to de-encapsulate SNAP frames, only do so if
380  *        the OUI is 00:00:00 or 00:00:f8, leave others alone.  The old
381  *        behaviour broke CDP (Cisco Discovery Protocol).
382  *      o Use dev instead of priv for free_irq() as well as
383  *        request_irq() (oops).
384  *      o Attempt to reset rather than giving up if we get too many
385  *        IRQs.
386  *      o Changed semantics of __orinoco_down() so it can be called
387  *        safely with hw_unavailable set.  It also now clears the
388  *        linkstatus (since we're going to have to reassociate).
389  *
390  * v0.13d -> v0.13e - 12 May 2003 - David Gibson
391  *      o Support for post-2.5.68 return values from irq handler.
392  *      o Fixed bug where underlength packets would be double counted
393  *        in the rx_dropped statistics.
394  *      o Provided a module parameter to suppress linkstatus messages.
395  *
396  * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
397  *      o Replaced priv->connected logic with netif_carrier_on/off()
398  *        calls.
399  *      o Remove has_ibss_any and never set the CREATEIBSS RID when
400  *        the ESSID is empty.  Too many firmwares break if we do.
401  *      o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
402  *        __devinitdata from PCI ID tables, use free_netdev().
403  *      o Enabled shared-key authentication for Agere firmware (from
404  *        Robert J. Moore <Robert.J.Moore AT allanbank.com>
405  *      o Move netif_wake_queue() (back) to the Tx completion from the
406  *        ALLOC event.  This seems to prevent/mitigate the rolling
407  *        error -110 problems at least on some Intersil firmwares.
408  *        Theoretically reduces performance, but I can't measure it.
409  *        Patch from Andrew Tridgell <tridge AT samba.org>
410  *
411  * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
412  *      o Correctly turn off shared-key authentication when requested
413  *        (bugfix from Robert J. Moore).
414  *      o Correct airport sleep interfaces for current 2.6 kernels.
415  *      o Add code for key change without disabling/enabling the MAC
416  *        port.  This is supposed to allow 802.1x to work sanely, but
417  *        doesn't seem to yet.
418  *
419  * TODO
420  *      o New wireless extensions API (patch from Moustafa
421  *        Youssef, updated by Jim Carter and Pavel Roskin).
422  *      o Handle de-encapsulation within network layer, provide 802.11
423  *        headers (patch from Thomas 'Dent' Mirlacher)
424  *      o RF monitor mode support
425  *      o Fix possible races in SPY handling.
426  *      o Disconnect wireless extensions from fundamental configuration.
427  *      o (maybe) Software WEP support (patch from Stano Meduna).
428  *      o (maybe) Use multiple Tx buffers - driver handling queue
429  *        rather than firmware.

432 /* Locking and synchronization:
433  *
434  * The basic principle is that everything is serialized through a
435  * single spinlock, priv->lock.  The lock is used in user, bh and irq
436  * context, so when taken outside hardirq context it should always be
437  * taken with interrupts disabled.  The lock protects both the
438  * hardware and the struct orinoco_private.
439  *
440  * Another flag, priv->hw_unavailable indicates that the hardware is
441  * unavailable for an extended period of time (e.g. suspended, or in
442  * the middle of a hard reset).  This flag is protected by the
443  * spinlock.  All code which touches the hardware should check the
444  * flag after taking the lock, and if it is set, give up on whatever
445  * they are doing and drop the lock again.  The orinoco_lock()
446  * function handles this (it unlocks and returns -EBUSY if
447  * hw_unavailable is non-zero).
