| 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. |
