Subject: [dpdk-dev] [PATCH v2 14/16] mlx5: enable multi packet send WR in TX CQ
Date: Fri, 30 Oct 2015 19:55:17 +0100 [thread overview]
Message-ID: <1446231319-8185-15-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1446231319-8185-1-git-send-email-adrien.mazarguil@6wind.com>
For adapters that support it, this flag improves performance outside of VF
context.
