Subject: [dpdk-dev] [PATCH 19/28] net/mlx5: func to create Rx verbs completion queue
Date: Mon, 22 Jul 2019 09:13:06 +0000 [thread overview]
Message-ID: <1563786795-14027-20-git-send-email-matan@mellanox.com> (raw)
In-Reply-To: <1563786795-14027-1-git-send-email-matan@mellanox.com>
From: Dekel Peled <dekelp@mellanox.com>
Verbs CQ for RxQ is created inside function mlx5_rxq_obj_new().
This patch moves the creation of CQ to dedicated function
mlx5_ibv_cq_new().
