Increase the completion queue size to prevent overflow. Under reasonably
unlikely circumstances - lots of single-fragment packets being sent, a
significant number of packets being received, while the interrupt handler
was unable to process the completion queue - the completion queue could
overflow, which would result in the interface locking up.
