From 34356f64ac0df2326fa50e2d4bca6f7c03ed16c1 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 29 Dec 2015 17:01:30 +0200 Subject: IB/mlx5: Unify CQ create flags check The create_cq() can receive creation flags which were used differently by two commits which added create_cq extended command and cross-channel. The merged code caused to not accept any flags at all. This patch unifies the check into one function and one return error code.
