Mike Marciniszyn 1ee9e2aa7b IPoIB: Fix send lockup due to missed TX completion ... Commit f0dc117abd ("IPoIB: Fix TX queue lockup with mixed UD/CM traffic") attempts to solve an issue where unprocessed UD send completions can deadlock the netdev. The patch doesn't fully resolve the issue because if more than half the tx_outstanding's were UD and all of the destinations are RC reachable, arming the CQ doesn't solve the issue. This patch uses the IB_CQ_REPORT_MISSED_EVENTS on the ib_req_notify_cq(). If the rc is above 0, the UD send cq completion callback is called directly to re-arm the send completion timer. This issue is seen in very large parallel filesystem deployments and the patch has been shown to correct the issue.
