Subject: RDMA/irdma: Return correct WC error for bind operation failure
Git-commit: dcb23bbb1de7e009875fdfac2b8a9808a9319cc6
Patch-mainline: v6.0
References: git-fixes
When a QP and a MR on a local host are in different PDs, the HW generates
an asynchronous event (AE). The same AE is generated when a QP and a MW
are in different PDs during a bind operation. Return the more appropriate
IBV_WC_MW_BIND_ERR for the latter case by checking the OP type from the
CQE in error.
Fixes: 551c46edc769 ("RDMA/irdma: Add user/kernel shared libraries")
