If we have a flow rule in the following form:
actions=strip_vlan,set_tunnel:0x3e9,15,16,17 (Where port 15, 16 and 17 are
VXLAN tunnels with different tunnelling information)
A packet which will hit that specific flow will only be sent out encapsulated
with the first tunnelling information.
This patch saves the initial packet vport, source port and NIC index for
further use of the currently implemented pipeline and ignores the latter if it
is the last tunnelling port.

This patch should also be applied on 2.4
v4 Relax condition when saving ports
v3 Fix formatting
v2 Address comments
