[ewg] ***SPAM*** CQ moderation parameters patch in OFED 1.3 effects latency

[Or Gerlitz]

OK, I see 10us difference in a udp ping pong latency test between the 
case where ethtool sets interrupt moderation to (10,16) vs (10,1)

$ ethtool -C ib1 adaptive-rx on rx-usecs 10 rx-frames 16  --> 9us
$ ethtool -C ib1 adaptive-rx on rx-usecs 10 rx-frames 1   --> 19us
Or.
