Unlike the older cards, the new ones are programmed * entirely via a firmware-driven controller called the Hermes. * Unfortunately, Lucent will not release the Hermes programming manual * without an NDA (if at all). What they do release is an API library * called the HCF (Hardware Control Functions) which is supposed to * do the device-specific operations of a device driver for you. The * publicly available version of the HCF library (the 'HCF Light') is * a) extremely gross, b) lacks certain features, particularly support * for 802.11 frames, and c) is contaminated by the GNU Public License. * * This driver does not use the HCF or HCF Light at all. Instead, it * programs the Hermes controller directly, using information gleaned * from the HCF Light code and corresponding documentation. */ #define WI_HERMES_AUTOINC_WAR /* Work around data write autoinc bug. */ #define WI_HERMES_STATS_WAR /* Work around stats counter bug. */ #include "bpfilter.h" #include #include #include #include #include #include #include #include #include #include #include #include #include #ifdef INET #include #include #include #include #include #endif #include #if NBPFILTER > 0 #include #endif #include #include #include #include #include #include #define BPF_MTAP(if,mbuf) bpf_mtap((if)->if_bpf, (mbuf)) #define BPFATTACH(if_bpf,if,dlt,sz) #define STATIC #ifdef WIDEBUG u_int32_t widebug = WIDEBUG;
