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 4946492Swpaul * publically 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. Instead, it 5446492Swpaul * programs the Hermes controller directly, using information gleaned 5546492Swpaul * from the HCF Light code and corresponding documentation. 5646492Swpaul * 5795534Simp * This driver supports the ISA, PCMCIA and PCI versions of the Lucent 5895534Simp * WaveLan cards (based on the Hermes chipset), as well as the newer 5995534Simp * Prism 2 chipsets with firmware from Intersil and Symbol. 6046492Swpaul */ 6146492Swpaul 62113038Sobrien#include <sys/cdefs.h> 63113038Sobrien__FBSDID("$FreeBSD: head/sys/dev/wi/if_wi.c 228621 2011-12-17 10:23:17Z bschmidt $");
