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.
