REVISION SUMMARY
  This message is used by the VF to request that its RX and TX
  queues be associated with particular MSI-X vectors.  This
  configuration is performed via a fairly complicated linked-list
  mechanism in the hardware.  The linked list is built up backwards
  (from the tail to the head) as it turns out to simplify the logic
  significantly.
