[dpdk-dev] [PATCH v2 0/6] support i40e QinQ stripping and insertion

[Helin Zhang]

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.
