43 | /* | |
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 | |
cbe85c04 | 51 | * publicly available version of the HCF library (the 'HCF Light') is |
984263bc MD |
52 | * a) extremely gross, b) lacks certain features, particularly support |
53 | * for 802.11 frames, and c) is contaminated by the GNU Public License. | |
54 | * | |
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. | |
58 | * | |
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. | |
