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