  The symptoms are:
1) It never sends a transmit complete interrupt, only early transmit
interrupts (if requested, if not it does nothing).
2) It *does* clear the owner bit on the setup packet. 
3) It fails to idle with transmit status RUNNING-CLOSE-CLEAR OWNER and
receive status RUNNING-WAIT.
4) The SROM reports bogus GPR media
