Subject: [PATCH 29/33] net/mlx5: Fix error flow in CREATE_QP command

From: Moni Shoua <[email-masked]>
Date: Mon, 4 Dec 2017 08:59:25 +0200

[ Upstream commit dbff26e44dc3ec4de6578733b054a0114652a764 ]

In error flow, when DESTROY_QP command should be executed, the wrong
mailbox was set with data, not the one that is written to hardware,
Fix that.

Fixes: 09a7d9eca1a6 '{net,IB}/mlx5: QP/XRCD commands via mlx5 ifc'
