From dcb23bbb1de7e009875fdfac2b8a9808a9319cc6 Mon Sep 17 00:00:00 2001 From: Sindhu-Devale Date: Tue, 6 Sep 2022 17:32:42 -0500 Subject: [PATCH] RDMA/irdma: Return correct WC error for bind operation failure 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.
