Steve Wise 5cd2fe6d54 RDS/IW+IB: Set recv ring low water mark to 1/2 full. 
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.
