72 | /* |
73 | * The WaveLAN/IEEE adapter is the second generation of the WaveLAN |
74 | * from Lucent. Unlike the older cards, the new ones are programmed |
75 | * entirely via a firmware-driven controller called the Hermes. |
76 | * Unfortunately, Lucent will not release the Hermes programming manual |
77 | * without an NDA (if at all). What they do release is an API library |
78 | * called the HCF (Hardware Control Functions) which is supposed to |
79 | * do the device-specific operations of a device driver for you. The |
80 | * publically available version of the HCF library (the 'HCF Light') is |
81 | * a) extremely gross, b) lacks certain features, particularly support |
82 | * for 802.11 frames, and c) is contaminated by the GNU Public License. |
83 | * |
84 | * This driver does not use the HCF or HCF Light at all. Instead, it |
85 | * programs the Hermes controller directly, using information gleaned |
86 | * from the HCF Light code and corresponding documentation. |
87 | * |
88 | * This driver supports both the PCMCIA and ISA versions of the |
89 | * WaveLAN/IEEE cards. Note however that the ISA card isn't really |
90 | * anything of the sort: it's actually a PCMCIA bridge adapter |
91 | * that fits into an ISA slot, into which a PCMCIA WaveLAN card is |
92 | * inserted. Consequently, you need to use the pccard support for |
93 | * both the ISA and PCMCIA adapters. |
