This patch simply fixes a bug on the rx vlan stripping path (where valid vlan_tci stripped is overwritten unconditionally later on the rx path in the original vmxnet3 pmd driver). All the other pmd drivers are doing the same thing in terms of translating descriptor status to rte_mbuf flags for vlan stripping.
I was thinking that there are many fields in a pktmbuf and rather than individually
setting them (like tci). The code should call the common rte_pktmbuf_reset before setting
the fields. That way when someone adds a field to mbuf they don't have to chasing
through every driver that does it's own initialization.
