Unlike the older cards, the new ones are programmed * entirely via a firmware-driven controller called the Hermes. * Unfortunately, Lucent will not release the Hermes programming manual * without an NDA (if at all). What they do release is an API library * called the HCF (Hardware Control Functions) which is supposed to * do the device-specific operations of a device driver for you. The * publically available version of the HCF library (the 'HCF Light') is * a) extremely gross, b) lacks certain features, particularly support * for 802.11 frames, and c) is contaminated by the GNU Public License. * * This driver does not use the HCF or HCF Light at all. Instead, it * programs the Hermes controller directly, using information gleaned * from the HCF Light code and corresponding documentation. * * This driver supports the ISA, PCMCIA and PCI versions of the Lucent * WaveLan cards (based on the Hermes chipset), as well as the newer * Prism 2 chipsets with firmware from Intersil and Symbol. */ #include __FBSDID("$FreeBSD$");
