-/* orinoco_cs.c 0.04 - (formerly known as dldwd_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.

-/* Notes on locking:
- *
- * The basic principle of operation is that everything except the
- * interrupt handler is serialized through a single spinlock in the
- * dldwd_priv_t 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.
- *
- * For the moment access to the device statistics from the interrupt
- * handler is unsafe - we just put up with any resulting errors in the
- * statisics. FIXME: This should probably be changed to store the
- * stats in atomic types.
- *
- * EXCEPT 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, when we
- * don't care about that.*/

-/*
- * Tentative changelog...
- *
- * v0.01 -> v0.02 - 21/3/2001 - Jean II
- * o Allow to use regular ethX device name instead of dldwdX
- * o Warning on IBSS with ESSID=any for firmware 6.06
- * o Put proper range.throughput values (optimistic)
- * o IWSPY support (IOCTL and stat gather in Rx path)
- * o Allow setting frequency in Ad-Hoc mode
- * o Disable WEP setting if !has_wep to work on old firmware
- * o Fix txpower range
- * o Start adding support for Samsung/Compaq firmware
- *
- * v0.02 -> v0.03 - 23/3/2001 - Jean II
- * o Start adding Symbol support - need to check all that
- * o Fix Prism2/Symbol WEP to accept 128 bits keys
- * o Add Symbol WEP (add authentication type)
- * o Add Prism2/Symbol rate
- * o Add PM timeout (holdover duration)
- * o Enable "iwconfig eth0 key off" and friends (toggle flags)
- * o Enable "iwconfig eth0 power unicast/all" (toggle flags)
- * o Try with an intel card. It report firmware 1.01, behave like
- * an antiquated firmware, however on windows it says 2.00. Yuck !
- * o Workaround firmware bug in allocate buffer (Intel 1.01)
- * o Finish external renaming to orinoco...
- * o Testing with various Wavelan firmwares
- *
- * v0.03 -> v0.04 - 30/3/2001 - Jean II
- * o Update to Wireless 11 -> add retry limit/lifetime support
- * o Tested with a D-Link DWL 650 card, fill in firmware support
- * o Warning on Vcc mismatch (D-Link 3.3v card in Lucent 5v only slot)
- * o Fixed the Prims2 WEP bugs that I introduced in v0.03 :-(
- * It work on D-Link *only* after a tcpdump. Weird...
- * And still doesn't work on Intel card. Grrrr...
- * o Update the mode after a setport3
- * o Add preamble setting for Symbol cards (not yet enabled)
- * o Don't complain as much about Symbol cards...
- *
- * v0.04 -> v0.04b - 22/4/2001 - David Gibson
- * o Removed the 'eth' parameter - always use ethXX as the
- * interface name instead of dldwdXX. The other was racy
- * anyway.
- * o Clean up RID definitions in hermes.h, other cleanups
- *
- * v0.04b -> v0.04c - 24/4/2001 - Jean II
- * o Tim Hurley <timster@seiki.bliztech.com> reported a D-Link card
- * with vendor 02 and firmware 0.08. Added in the capabilities...
- * o Tested Lucent firmware 7.28, everything works...
- *
- * TODO - Jean II
- * o inline functions (lot's of candidate, need to reorder code)
- * o Separate Pcmcia specific code to help Airport/Mini PCI driver
- * o Test PrismII/Symbol cards & firmware versions
