Unlike the older cards, the new ones are programmed 46 * entirely via a firmware-driven controller called the Hermes. 47 * Unfortunately, Lucent will not release the Hermes programming manual 48 * without an NDA (if at all). What they do release is an API library 49 * called the HCF (Hardware Control Functions) which is supposed to 50 * do the device-specific operations of a device driver for you. The 51 * publically available version of the HCF library (the 'HCF Light') is 52 * a) extremely gross, b) lacks certain features, particularly support 53 * for 802.11 frames, and c) is contaminated by the GNU Public License. 54 * 55 * This driver does not use the HCF or HCF Light at all. Instead, it 56 * programs the Hermes controller directly, using information gleaned 57 * from the HCF Light code and corresponding documentation. 58 * 59 * This driver supports both the PCMCIA and ISA versions of the 60 * WaveLAN/IEEE cards. Note however that the ISA card isn't really 61 * anything of the sort: it's actually a PCMCIA bridge adapter 62 * that fits into an ISA slot, into which a PCMCIA WaveLAN card is 63 * inserted. Consequently, you need to use the pccard support for 64 * both the ISA and PCMCIA adapters. 65 */ 66 67 /* 68 * FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the 69 * Oslo IETF plenary meeting. 70 */ 71 72 #include <sys/cdefs.h> 73 __KERNEL_RCSID(0, "$NetBSD: wi.c,v 1.178 2004/07/22 20:34:52 mycroft Exp $");
