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