RE: small change in the connected mode draft

I think that this is reasonable amendment. Being practical, I don't
think that IPoIB-CM will be widely used over WANs or long latency
fabrics. To me it looks something very data center oriented, something
like Jumbo frames in Ethernet. 

Other than that, IB is mostly a lossless fabric, so I wouldn't expect to
see that many of retransmissions in RC anyway.
