Unlike the older cards, the new ones are programmed 82 * entirely via a firmware-driven controller called the Hermes. 83 * Unfortunately, Lucent will not release the Hermes programming manual 84 * without an NDA (if at all). What they do release is an API library 85 * called the HCF (Hardware Control Functions) which is supposed to 86 * do the device-specific operations of a device driver for you. The 87 * publically available version of the HCF library (the 'HCF Light') is 88 * a) extremely gross, b) lacks certain features, particularly support 89 * for 802.11 frames, and c) is contaminated by the GNU Public License. 90 * 91 * This driver does not use the HCF or HCF Light at all. Instead, it 92 * programs the Hermes controller directly, using information gleaned 93 * from the HCF Light code and corresponding documentation. 94 * 95 * This driver supports both the PCMCIA and ISA versions of the 96 * WaveLAN/IEEE cards. Note however that the ISA card isn't really 97 * anything of the sort: it's actually a PCMCIA bridge adapter 98 * that fits into an ISA slot, into which a PCMCIA WaveLAN card is 99 * inserted. Consequently, you need to use the pccard support for 100 * both the ISA and PCMCIA adapters. 101 */ 102 103 /* 104 * FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the 105 * Oslo IETF plenary meeting. 106 */ 107 108 #include <sys/cdefs.h> 109 __KERNEL_RCSID(0, "$NetBSD: wi.c,v 1.159.2.2 2004/07/23 23:26:50 he Exp $");
