Unlike the older cards, the new ones are programmed 75 * entirely via a firmware-driven controller called the Hermes. 76 * Unfortunately, Lucent will not release the Hermes programming manual 77 * without an NDA (if at all). What they do release is an API library 78 * called the HCF (Hardware Control Functions) which is supposed to 79 * do the device-specific operations of a device driver for you. The 80 * publically available version of the HCF library (the 'HCF Light') is 81 * a) extremely gross, b) lacks certain features, particularly support 82 * for 802.11 frames, and c) is contaminated by the GNU Public License. 83 * 84 * This driver does not use the HCF or HCF Light at all. Instead, it 85 * programs the Hermes controller directly, using information gleaned 86 * from the HCF Light code and corresponding documentation. 87 * 88 * This driver supports both the PCMCIA and ISA versions of the 89 * WaveLAN/IEEE cards. Note however that the ISA card isn't really 90 * anything of the sort: it's actually a PCMCIA bridge adapter 91 * that fits into an ISA slot, into which a PCMCIA WaveLAN card is 92 * inserted. Consequently, you need to use the pccard support for 93 * both the ISA and PCMCIA adapters. 94 */ 95 96 /* 97 * FreeBSD driver ported to NetBSD by Bill Sommerfeld in the back of the 98 * Oslo IETF plenary meeting. 99 */ 100 101 #include <sys/cdefs.h> 102 __KERNEL_RCSID(0, "$NetBSD: wi.c,v 1.253 2019/05/28 07:41:48 msaitoh Exp $");
