> Subject: [PATCH v4 1/2] app/testpmd: add VXLAN encap/decap support
>=20
> Due to the complex VXLAN_ENCAP flow action and based on the fact testpmd
> does not allocate memory, this patch adds a new command in testpmd to
> initialise a global structure containing the necessary information to mak=
e the
> outer layer of the packet.  This same global structure will then be used =
by the
> flow command line in testpmd when the action vxlan_encap will be parsed, =
at
> this point, the conversion into such action becomes trivial.
>=20
> This global structure is only used for the encap action.
