119 * v0.05d -> v0.06 - 25/5/2001 - Jean II
120 * Original patch from "Hong Lin" <alin AT redhat.com>,
121 * "Ian Kinner" <ikinner AT redhat.com>
122 * and "David Smith" <dsmith AT redhat.com>
123 * o Init of priv->tx_rate_ctrl in firmware specific section.

135 * v0.06 -> v0.06b - 25/5/2001 - Jean II
136 * o IBSS on Symbol use port_mode = 4. Please don't ask...
138 * v0.06b -> v0.06c - 29/5/2001 - Jean II
139 * o Show first spy address in /proc/net/wireless for IBSS mode as well
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'
143 * wishes to reduce the number of unnecessary messages.
144 * o Removed bogus message on CRC error.
145 * o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
146 * <willwaghorn AT yahoo.co.uk>
147 * o Slight cleanup/re-arrangement of firmware detection code.
149 * v0.06d -> v0.06e - 1/8/2001 - David Gibson
150 * o Removed some redundant global initializers (orinoco_cs.c).
151 * o Added some module metadata
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.
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.
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).
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
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.
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.
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)
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)
224 * v0.09 -> v0.09a - 2/1/2002 - David Gibson
225 * o Fixed stupid mistake in multicast list handling, triggering
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.
241 * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
242 * o Removed nested structures used for header parsing, so the
243 * driver should now work without hackery on ARM
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.
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).
254 * o Relegated Tx error messages to debug.
255 * o Cleaned up / corrected handling of allocation lengths.
256 * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
257 * o Change to using alloc_etherdev() for structure allocations.
258 * o Check for and drop undersized packets.
259 * o Fixed a race in stopping/waking the queue. This should fix
260 * the timeout problems (Pavel Roskin)
261 * o Reverted to netif_wake_queue() on the ALLOC event.
262 * o Fixes for recent Symbol firmwares which lack AP density
265 * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
266 * o Handle different register spacing, necessary for Prism 2.5
267 * PCI adaptors (Steve Hill).
268 * o Cleaned up initialization of card structures in orinoco_cs
269 * and airport. Removed card->priv field.
270 * o Make response structure optional for hermes_docmd_wait()
272 * o Added PCI id for Nortel emobility to orinoco_plx.c.
273 * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
274 * o Cleanups to firmware capability detection.
275 * o Arrange for orinoco_pci.c to override firmware detection.
276 * We should be able to support the PCI Intersil cards now.
277 * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
278 * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
280 * o Makefile changes for better integration into David Hinds
283 * v0.11a -> v0.11b - 1 May 2002 - David Gibson
284 * o Better error reporting in orinoco_plx_init_one()
285 * o Fixed multiple bad kfree() bugs introduced by the
286 * alloc_orinocodev() changes.
288 * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
289 * o Support changing the MAC address.
290 * o Correct display of Intersil firmware revision numbers.
291 * o Entirely revised locking scheme. Should be both simpler and
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
298 * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
299 * They didn't do anything.
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
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
312 * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
313 * o Fix hw->num_init testing code, so num_init is actually
315 * o Fix very stupid bug in orinoco_cs which broke compile with
317 * o Squashed a warning.
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.
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
328 * o Do firmware resets only in orinoco_init() and when waking
329 * the card from hard sleep.
331 * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
332 * o Re-introduced full resets (via schedule_task()) on Tx
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
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.
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
364 * o New orinoco_tmd.c init module from Joerg Dorchain for
365 * TMD7160 based PCI to PCMCIA bridges (similar to
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
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).
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.
396 * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
397 * o Replaced priv->connected logic with netif_carrier_on/off()
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>
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.
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:
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.
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).
