[dpdk-dev] [PATCH v7 3/3] app/testpmd: tunnel parsing protocols cleanup

From: Ophir Munk <ophirmu at 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.
It replaces all numeric values 4789 in their corresponding definition
RTE_VXLAN_GPE_DEFAULT_PORT.
It updates the 'csum parse-tunnel' documentation.
