[openib-general] Latest CM and retransmissions

[Hal Rosenstock]

Hi Sean,

With the latest CM changes (not sure when I last picked these up), I am
now seeing the following sequences. The times between the CM MADs are on
the order of 10s of usec. These sequences all refer to the same
connection. It seems that the retransmissions are occuring despite the
expected MAD being received.
