There is some information 54 * missing from the manual which one needs to know in order to make 55 * the chip function: 56 * 57 * - You must set bit 7 in the RX control register, otherwise the 58 * chip won't receive any packets. 59 * - You must initialize all 3 IPG registers, or you won't be able 60 * to send any packets. 61 * 62 * Note that this device appears to only support loading the station 63 * address via autload from the EEPROM (i.e. there's no way to manaully 64 * set it). 65 * 66 * (Adam Weinberger wanted me to name this driver if_gir.c.) 67 */ 68 69 /* 70 * Ported to OpenBSD 3/28/2004 by Greg Taleck <taleck (at) oz.net> 71 * with bits and pieces from the aue and url drivers. 72 */ 73 74 #include <sys/cdefs.h> 75 __KERNEL_RCSID(0, "$NetBSD: if_axe.c,v 1.4 2004/10/24 12:53:26 augustss Exp $");
