37 * Lucent WaveLAN/IEEE 802.11 PCMCIA driver.
39 * Original FreeBSD driver written by Bill Paul <wpaul@ctr.columbia.edu>
40 * Electrical Engineering Department
41 * Columbia University, New York City
45 * The WaveLAN/IEEE adapter is the second generation of the WaveLAN
46 * from Lucent. Unlike the older cards, the new ones are programmed
47 * entirely via a firmware-driven controller called the Hermes.
48 * Unfortunately, Lucent will not release the Hermes programming manual
49 * without an NDA (if at all). What they do release is an API library
50 * called the HCF (Hardware Control Functions) which is supposed to
51 * do the device-specific operations of a device driver for you. The
52 * publically available version of the HCF library (the 'HCF Light') is
53 * a) extremely gross, b) lacks certain features, particularly support
54 * for 802.11 frames, and c) is contaminated by the GNU Public License.
56 * This driver does not use the HCF or HCF Light at all. Instead, it
57 * programs the Hermes controller directly, using information gleaned
58 * from the HCF Light code and corresponding documentation.
60 * This driver supports the ISA, PCMCIA and PCI versions of the Lucent
61 * WaveLan cards (based on the Hermes chipset), as well as the newer
62 * Prism 2 chipsets with firmware from Intersil and Symbol.
