There is some information 55 * missing from the manual which one needs to know in order to make 56 * the chip function: 57 * 58 * - You must set bit 7 in the RX control register, otherwise the 59 * chip won't receive any packets. 60 * - You must initialize all 3 IPG registers, or you won't be able 61 * to send any packets. 62 * 63 * Note that this device appears to only support loading the station 64 * address via autload from the EEPROM (i.e. there's no way to manaully 65 * set it). 66 * 67 * (Adam Weinberger wanted me to name this driver if_gir.c.) 68 */ 69 70 /* 71 * Ported to OpenBSD 3/28/2004 by Greg Taleck <taleck (at) oz.net> 72 * with bits and pieces from the aue and url drivers. 73 */ 74 75 #include <sys/cdefs.h> 76 __KERNEL_RCSID(0, "$NetBSD: if_axe.c,v 1.13 2006/03/19 22:30:56 david Exp $");
