The bnxt driver is not correctly setting the receive VLAN offload
flags. When VLAN is offloaded the driver must set the
PKT_RX_VLAN_STRIPPED flag.
Actually, several drivers have the same bug, only most of the
Intel drivers look right. Any driver that sets vlan_tci is probably
stripping the tag, and should be setting RX_VLAN_STRIPPED.
To quote rte_mbuf.h:
/**
* The RX packet is a 802.1q VLAN packet, and the tci has been
* saved in in mbuf->vlan_tci.
* If the flag PKT_RX_VLAN_STRIPPED is also present, the VLAN
* header has been stripped from mbuf data, else it is still
* present.
