While troubleshooting some QinQ offloads with various Intel i40e firmware[1], it was
helpful to expose the outer vlan in the dump mbuf calls. This should be straightforward
to backport and happy to do the work if accepted. I understand that this may not be a
widely supported capability at this time, so we are okay if this is not accepted and
we just maintain a local patch.
