* Vendor specific commands. ASIX conveniently doesn't document the 'set
* NODEID' command in their datasheet (thanks a lot guys).
* To make handling these commands easier, I added some extra data which is
* decided by the axe_cmd() routine. Commands are encoded in 16 bits, with
* the format: LDCC. L and D are both nibbles in the high byte. L represents
* the data length (0 to 15) and D represents the direction (0 for vendor read,
* 1 for vendor write). CC is the command byte, as specified in the manual.
