I suggest title: "net/i40e: fix VLAN stripping in VF"
Will update the title and some wording in the commit log while merging.

And I assume this should be backported, so will add stable at dpdk.org tag,
but can you please confirm the Linux PF behavior was always same?

And if the Linux PF behavior was always same, should we add the DPDK commit as 
fixes commit, @Qi, @Jeff, what do you think?

Other question is, does Linux PF and DPDK PF behave differently on enabling VLAN 
stripping and should it be unified to be consistent?
