43: * Vendor specific commands
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.
