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 * Ax88178 and Ax88772 support backported from the OpenBSD driver. 72 * 2007/02/12, J.R.
