36 * ASIX Electronics AX88172 USB 2.0 ethernet driver. Used in the
37 * LinkSys USB200M and various other adapters.
39 * Manuals available from:
40 * http://www.asix.com.tw/datasheet/mac/Ax88172.PDF
41 * Note: you need the manual for the AX88170 chip (USB 1.x ethernet
42 * controller) to find the definitions for the RX control register.
43 * http://www.asix.com.tw/datasheet/mac/Ax88170.PDF
45 * Written by Bill Paul <wpaul@windriver.com>
51 * The AX88172 provides USB ethernet supports at 10 and 100Mbps.
52 * It uses an external PHY (reference designs use a RealTek chip),
53 * and has a 64-bit multicast hash filter. There is some information
54 * missing from the manual which one needs to know in order to make
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.
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
66 * (Adam Weinberger wanted me to name this driver if_gir.c.)
