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