OK, but that seems irrelevant to the discussion at hand.  In a case
like that I would expect you to keep track of the P_Key index to use
and not look it up again for every connection.

...in fact, why is ipoib_cm.c looking up the pkey index for every
connection?  Shouldn't it use the pkey index that datagram mode
already looked up?
