Subject[PATCH 3.16 077/136] IB/mlx5: Assign send CQ and recv CQ of UMR QP
3.16.54-rc1 review patch.  If anyone has any objections, please let me know.


From: Majd Dibbiny <>

commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 upstream.

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.

Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters")
