Are you referring to the patch as a whole or your comment is about the reset of vlan_tci on the "else" (no vlan tags stripped) path?  I am not sure I get your comments here.  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.

Since vlan_tci is initialized to zero by rte_pktmbuf layer,
the driver shouldn't be messing with it.
