Subject: [dpdk-dev] [PATCH v4 3/3] app/testpmd: reduce tunnel parsing code duplication
Date: Tue, 15 Sep 2020 13:17:17 +0000
Message-ID: <20200915131717.18252-4-ophirmu@nvidia.com> (raw)
In-Reply-To: <20200915131717.18252-1-ophirmu@nvidia.com>

From: Ophir Munk <ophirmu@mellanox.com>

This is a cleanup commit. It assembles all tunnel outer updates into one
function call to avoid code duplications.
It defines RTE_VXLAN_GPE_DEFAULT_PORT (4790) in accordance with all
other tunnel protocol definitions.
