The ethertype test suite requires many different internal runtime
vlan offload options to test ethertype configuration. The following patch
adds a new RxVlanOffloadOptions class that contains all the different
vlan configuration options available within testpmd. Additionally, an
extra method has beena added to adjust both the inner and outer tpids of
ingressing and egressing packets.
