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