Subject: RDMA/iwcm: iWARP connection timeouts shouldn't be reported as rejects
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=881a045fc5b454b57c69e010acecd5830d87e242;p=deliverable%2Flinux.git

RDMA/iwcm: iWARP connection timeouts shouldn't be reported as rejects

The iWARP CM should report timeouts as event RDMA_CM_EVENT_UNREACHABLE,
not event RDMA_CM_EVENT_REJECTED.
