| 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. |
