* Transmit and receive ring discriptor ---------------------------
* The QNA uses the flag, status1 and the valid bit as a handshake/semiphore
* The flag word is written on ( bits 15,15 set to 1 ) when it reads the
* descriptor. If the valid bit is set it considers the address to be valid.
* When it uses the buffer pointed to by the valid address it sets status word
