Subject: [dpdk-dev] [PATCH v2 1/4] net/mlx4: move rdma-core calls to separate file
Date: Fri, 26 Jan 2018 15:18:57 +0100	[thread overview]
Message-ID: <20180126141215.30395-2-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <20180126141215.30395-1-adrien.mazarguil@6wind.com>

This lays the groundwork for externalizing rdma-core as an optional
run-time dependency instead of a mandatory one.

No functional change.
