/*
* The AX88172 provides USB ethernet supports at 10 and 100Mbps.
* It uses an external PHY (reference designs use a RealTek chip),
* and has a 64-bit multicast hash filter. 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.)
