* Lucent WaveLAN/IEEE 802.11 PCMCIA driver for NetBSD.
*
* Original FreeBSD driver written by Bill Paul <wpaul@ctr.columbia.edu>
* Electrical Engineering Department
* Columbia University, New York City
*/
/*
* The WaveLAN/IEEE adapter is the second generation of the WaveLAN
* from Lucent. Unlike the older cards, the new ones are programmed
* entirely via a firmware-driven controller called the Hermes.
* Unfortunately, Lucent will not release the Hermes programming manual
* without an NDA (if at all). What they do release is an API library
* called the HCF (Hardware Control Functions) which is supposed to
* do the device-specific operations of a device driver for you. The
* publically available version of the HCF library (the 'HCF Light') is
* a) extremely gross, b) lacks certain features, particularly support
* for 802.11 frames, and c) is contaminated by the GNU Public License.
*
* This driver does not use the HCF or HCF Light at all. Instead, it
* programs the Hermes controller directly, using information gleaned
* from the HCF Light code and corresponding documentation.
*
* This driver supports both the PCMCIA and ISA versions of the
* WaveLAN/IEEE cards. Note however that the ISA card isn't really
* anything of the sort: it's actually a PCMCIA bridge adapter
* that fits into an ISA slot, into which a PCMCIA WaveLAN card is
* inserted. Consequently, you need to use the pccard support for
* both the ISA and PCMCIA adapters.
*/
/*
* FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the
* Oslo IETF plenary meeting.
