 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

 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'

 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
 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  *

 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

 290  *      o Correct display of Intersil firmware revision numbers.
 291  *      o Entirely revised locking scheme.  Should be both simpler and
 292  *         better.
 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).
