From d702be100eaf043b97687c050565c154a48d763d Mon Sep 17 00:00:00 2001 From: Majd Dibbiny Date: Mon, 30 Oct 2017 14:23:13 +0200 Subject: [PATCH] IB/mlx5: Assign send CQ and recv CQ of UMR QP [ Upstream commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 ] The UMR's QP is created by calling mlx5_ib_create_qp directly, and therefore the send CQ and the recv CQ on the ibqp weren't assigned. Assign them right after calling the mlx5_ib_create_qp to assure that any access to those pointers will work as expected and won't crash the system as might happen as part of reset flow.
