(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.
