This series of patches is the result of high scale testing on a large HPC system with a large attached Lustre file system. Several errors were found which had not been previously seen at smaller scales. In this case up to 1600 QPs on 1024 compute nodes attached to about 100 flash storage nodes. Each patch has it's own description. v3 Fixed an error in "Don't call rxe_requester from rxe_completer" Moved run_requester_again from a global to rxe_req_info.again. The control parameter has to be local to each qp. v2 Minor edits to some of the commit messages. Added a missing change to "Don't schedule rxe_completer...". Added a missing change to "Git rid of pkt resend on err". Added one additional commit.
