There is some information * missing from the manual which one needs to know in order to make * the chip function: * * - You must set bit 7 in the RX control register, otherwise the * chip won't receive any packets. * - You must initialize all 3 IPG registers, or you won't be able * to send any packets. * * Note that this device appears to only support loading the station * address via autload from the EEPROM (i.e. there's no way to manaully * set it). * * (Adam Weinberger wanted me to name this driver if_gir.c.) */ /* * Ported to OpenBSD 3/28/2004 by Greg Taleck * with bits and pieces from the aue and url drivers. */ #include "bpfilter.h" #include #include #include #include #include #include #include #include #include #include #include #include #include #if NBPFILTER > 0 #include #endif #ifdef INET #include #include #include #include #include #endif #include #include #include #include #include #include #include #include #ifdef AXE_DEBUG #define DPRINTF(x) do { if (axedebug) printf x;
