702  * are tagged with vlan 0. On an access vNIC (standalone or B

706  * default. But it also broke vlan sub-interfaces.
707  *
708  * The VIC adapter has "untag default vlan" ingress VLAN rewrite
709  * mode, which removes tags from these packets. VPP now includes
710  * a local patch for the enic driver to use this untag mode, so
711  * enabling vlan stripping is no longer needed. In future, the
712  * driver + dpdk will have an API to set the mode after
713  * rte_eal_init. Then, this note and local patch will be
