Unlike the older cards, the new ones are programmed 46 1.17.2.2 nathanw * entirely via a firmware-driven controller called the Hermes. 47 1.17.2.2 nathanw * Unfortunately, Lucent will not release the Hermes programming manual 48 1.17.2.2 nathanw * without an NDA (if at all). What they do release is an API library 49 1.17.2.2 nathanw * called the HCF (Hardware Control Functions) which is supposed to 50 1.17.2.2 nathanw * do the device-specific operations of a device driver for you. The 51 1.17.2.2 nathanw * publically available version of the HCF library (the 'HCF Light') is 52 1.17.2.2 nathanw * a) extremely gross, b) lacks certain features, particularly support 53 1.17.2.2 nathanw * for 802.11 frames, and c) is contaminated by the GNU Public License. 54 1.17.2.2 nathanw * 55 1.17.2.2 nathanw * This driver does not use the HCF or HCF Light at all. Instead, it 56 1.17.2.2 nathanw * programs the Hermes controller directly, using information gleaned 57 1.17.2.2 nathanw * from the HCF Light code and corresponding documentation. 58 1.17.2.2 nathanw * 59 1.17.2.2 nathanw * This driver supports both the PCMCIA and ISA versions of the 60 1.17.2.2 nathanw * WaveLAN/IEEE cards. Note however that the ISA card isn't really 61 1.17.2.2 nathanw * anything of the sort: it's actually a PCMCIA bridge adapter 62 1.17.2.2 nathanw * that fits into an ISA slot, into which a PCMCIA WaveLAN card is 63 1.17.2.2 nathanw * inserted. Consequently, you need to use the pccard support for 64 1.17.2.2 nathanw * both the ISA and PCMCIA adapters. 65 1.17.2.2 nathanw */ 66 1.17.2.2 nathanw 67 1.17.2.2 nathanw /* 68 1.17.2.2 nathanw * FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the 69 1.17.2.2 nathanw * Oslo IETF plenary meeting. 70 1.17.2.2 nathanw */ 71 1.17.2.2 nathanw 72 1.17.2.8 nathanw #include <sys/cdefs.h> 73 1.17.2.16 nathanw __KERNEL_RCSID(0, "$NetBSD: wi.c,v 1.17.2.16 2002/08/13 02:19:30 nathanw Exp $");
