Unlike the older cards, the new ones are programmed 4446492Swpaul * entirely via a firmware-driven controller called the Hermes. 4546492Swpaul * Unfortunately, Lucent will not release the Hermes programming manual 4646492Swpaul * without an NDA (if at all). What they do release is an API library 4746492Swpaul * called the HCF (Hardware Control Functions) which is supposed to 4846492Swpaul * do the device-specific operations of a device driver for you. The 49298955Spfg * publicly available version of the HCF library (the 'HCF Light') is 5047401Swpaul * a) extremely gross, b) lacks certain features, particularly support 5146492Swpaul * for 802.11 frames, and c) is contaminated by the GNU Public License. 5246492Swpaul * 5346492Swpaul * This driver does not use the HCF or HCF Light at all.
