2009-04-09	RDS/IW+IB: Set recv ring low water mark to 1/2 full.	Steve Wise	1	-1/+1
	Currently the recv ring low water mark is 1/4 the depth. Performance measurements show that this limits iWARP throughput by flow controlling the rds-stress senders. Setting it to 1/2 seems to max the T3 performance. I tried even higher levels but that didn't help and it started to increase the rds thread cpu utilization.
