[v4,3/3] app/testpmd: reduce tunnel parsing code duplication
Checks
Commit Message
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.
