 * 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.
