Log Message:
reduce Tx/Rx maximum number of words (as PDF says) in one DMA
transaction to 8.  value 32 triggers occational watchdog() Tx
timeout when higher system load.  This symptom is observed in
ipforwarding across two PCI devices case so far, and it remains
unidentified what really happens for Tx DMA activity.  16 seems
ok, 8 is conservative and heuristic value.  may need more adjustment
work in other parts.
