Unlike the older cards, the new ones are programmed 4646492Swpaul * entirely via a firmware-driven controller called the Hermes. 4746492Swpaul * Unfortunately, Lucent will not release the Hermes programming manual 4846492Swpaul * without an NDA (if at all). What they do release is an API library 4946492Swpaul * called the HCF (Hardware Control Functions) which is supposed to 5046492Swpaul * do the device-specific operations of a device driver for you. The 5146492Swpaul * publically available version of the HCF library (the 'HCF Light') is 5247401Swpaul * a) extremely gross, b) lacks certain features, particularly support 5346492Swpaul * for 802.11 frames, and c) is contaminated by the GNU Public License. 5446492Swpaul * 5546492Swpaul * This driver does not use the HCF or HCF Light at all. Instead, it 5646492Swpaul * programs the Hermes controller directly, using information gleaned 5746492Swpaul * from the HCF Light code and corresponding documentation. 5846492Swpaul * 5995534Simp * This driver supports the ISA, PCMCIA and PCI versions of the Lucent 6095534Simp * WaveLan cards (based on the Hermes chipset), as well as the newer 6195534Simp * Prism 2 chipsets with firmware from Intersil and Symbol. 6246492Swpaul */ 6346492Swpaul 64113038Sobrien#include <sys/cdefs.h> 65113038Sobrien__FBSDID("$FreeBSD: head/sys/dev/wi/if_wi.c 144167 2005-03-26 23:43:54Z sam $");
