Applied to dpdk-next-net/master, thanks.
In a quick glance, following PMDs as well set "PKT_RX_VLAN" but not
"PKT_RX_VLAN_STRIPPED", their maintainers are cc'ed, can you please double check:
- bnx2x
- qede (it doesn't set 'vlan_tci' if not stripped, should be fixed)
- dpaa2
- dpaa (is 'vlan_tci' set?)
- avp
- fm10k
