44 1.17.2.2 nathanw * The WaveLAN/IEEE adapter is the second generation of the WaveLAN
45 1.17.2.2 nathanw * from Lucent. Unlike the older cards, the new ones are programmed
46 1.17.2.2 nathanw * entirely via a firmware-driven controller called the Hermes.
47 1.17.2.2 nathanw * Unfortunately, Lucent will not release the Hermes programming manual
48 1.17.2.2 nathanw * without an NDA (if at all). What they do release is an API library
49 1.17.2.2 nathanw * called the HCF (Hardware Control Functions) which is supposed to
50 1.17.2.2 nathanw * do the device-specific operations of a device driver for you. The
51 1.17.2.2 nathanw * publically available version of the HCF library (the 'HCF Light') is
52 1.17.2.2 nathanw * a) extremely gross, b) lacks certain features, particularly support
53 1.17.2.2 nathanw * for 802.11 frames, and c) is contaminated by the GNU Public License.
54 1.17.2.2 nathanw *
55 1.17.2.2 nathanw * This driver does not use the HCF or HCF Light at all. Instead, it
56 1.17.2.2 nathanw * programs the Hermes controller directly, using information gleaned
57 1.17.2.2 nathanw * from the HCF Light code and corresponding documentation.
58 1.17.2.2 nathanw *
59 1.17.2.2 nathanw * This driver supports both the PCMCIA and ISA versions of the
60 1.17.2.2 nathanw * WaveLAN/IEEE cards. Note however that the ISA card isn't really
61 1.17.2.2 nathanw * anything of the sort: it's actually a PCMCIA bridge adapter
62 1.17.2.2 nathanw * that fits into an ISA slot, into which a PCMCIA WaveLAN card is
63 1.17.2.2 nathanw * inserted. Consequently, you need to use the pccard support for
64 1.17.2.2 nathanw * both the ISA and PCMCIA adapters.
