As i40e hardware can be reconfigured to support QinQ stripping and insertion, this patch set is to enable that together with using the reserved 16 bits in 'struct rte_mbuf' for the second vlan tag. Corresponding command is added in testpmd for testing. Note that no need to rework vPMD, as nothings used in it changed.
v2 changes: * Added more commit logs of which commit it fix for. * Fixed a typo. * Kept the original RX/TX offload flags as they were, added new flags after with new bit masks, for ABI compatibility. * Supported double vlan stripping/insertion in examples/ipv4_multicast. v3 changes: * update documentation (Testpmd Application User Guide).
