  I got some report for users that VLAN insertion was not working as the
only thing they could see in verbose mode was a 0x0800 ethertype even
though the RTE_MBUF_F_TX_VLAN flag was shown.

Dump the VLAN TCI from mbuf metadata when VLAN insertion is requested.
This should enhance the situation.

Before:
  src=76:4E:EA:3F:78:1D - dst=50:7C:6F:3C:10:5B - pool=mb_pool_1 -
	type=0x0800 - length=64 - nb_segs=1 -
	sw ptype: L2_ETHER L3_IPV4 L4_UDP  -
	l2_len=14 - l3_len=20 - l4_len=8 - Send queue=0x0
  ol_flags: RTE_MBUF_F_TX_VLAN RTE_MBUF_F_TX_L4_NO_CKSUM

After:
  src=76:4E:EA:3F:78:1D - dst=50:7C:6F:3C:10:5B - pool=mb_pool_1 -
	type=0x0800 - length=64 - nb_segs=1 - VLAN tci=0x2a -
	sw ptype: L2_ETHER L3_IPV4 L4_UDP  -
	l2_len=14 - l3_len=20 - l4_len=8 - Send queue=0x0
  ol_flags: RTE_MBUF_F_TX_VLAN RTE_MBUF_F_TX_L4_NO_CKSUM
