From: Bill Hong <bh...@brocade.com>
A PMD might use rte_vlan_insert to implement Tx VLAN offload. Typically
the PMD will insert the VLAN header in the transmit path and then attempt
to send the packets. If this fails, the packets are returned to
the application which may attempt to send these packets again. If the
PKT_TX_VLAN flag is not cleared, the transmit path may attempt to insert
the VLAN header again.
Fixes: 47aa48b969f8 ("net: fix stripped VLAN flag for offload emulation");
