- /* orinoco.c 0.09b - (formerly known as dldwd_cs.c and orinoco_cs.c)
- *
- * A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
- * as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
- * EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and others).
- * It should also be usable on various Prism II based cards such as the
- * Linksys, D-Link and Farallon Skyline. It should also work on Symbol
- * cards such as the 3Com AirConnect and Ericsson WLAN.

- *
- * 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 unecessary messages.
- * o Removed bogus message on CRC error.
- * o Merged fixeds for v0.08 Prism 2 firmware from William Waghorn
- * <willwaghorn@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 metadataa
- *
- * 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@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
- * realised 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 brdge) cards.
- * o Changed to using the new type-facist 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 normalisation of signel 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 redundand 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.
- *
- * TODO
- * o Find and kill remaining Tx timeout problems
- * o Fix WEP / order of iwconfig wierdness on Intersil firmware
- * o Convert /proc debugging stuff to seqfile
- * o Re-assess our encapsulation detection strategy
- * o Handle de-encapsulation within NET framework, provide 802.11
- * headers
- * o Fix possible races in SPY handling.
- * o Take the xmit lock when calling orinoco_reset from an
- * ioctl(), because that protects the multicast list.
- * o Fix allocation lengths.
- */
- /* Notes on locking:
- *
- * The basic principle of operation is that everything except the
- * interrupt handler is serialized through a single spinlock in the
- * struct orinoco_private structure, using dldwd_lock() and
- * dldwd_unlock() (which in turn use spin_lock_bh() and
- * spin_unlock_bh()).
- *
- * The kernel's IRQ handling stuff ensures that the interrupt handler
- * does not re-enter itself. The interrupt handler is written such
- * that everything it does is safe without a lock: chiefly this means
- * that the Rx path uses one of the Hermes chipset's BAPs while
- * everything else uses the other.
- *
- * Actually, strictly speaking, the updating of the statistics from
- * the interrupt handler isn't safe without a lock. However the worst
- * that can happen is that we perturb the packet/byte counts slightly.
- * We could fix this to use atomic types, but it's probably not worth
- * it.
- *
- * The big exception is that that we don't want the irq handler
- * running when we actually reset or shut down the card, because
- * strange things might happen (probably the worst would be one packet
- * of garbage, but you can't be too careful). For this we use
- * __dldwd_stop_irqs() which will set a flag to disable the interrupt
- * handler, and wait for any outstanding instances of the handler to
- * complete. THIS WILL LOSE INTERRUPTS! so it shouldn't be used except
- * for resets, where losing a few interrupts is acceptable. */
