765 * are tagged with vlan 0. On an access vNIC (standalone or B
766 * series "blade" server), packets on the default/native VLAN
767 * are tagged with that vNIC's VLAN. VPP expects these packets
768 * to be untagged, and previously enabled VLAN strip on VIC by
769 * default. But it also broke vlan sub-interfaces.
771 * The VIC adapter has "untag default vlan" ingress VLAN rewrite
772 * mode, which removes tags from these packets. VPP now includes
773 * a local patch for the enic driver to use this untag mode, so
774 * enabling vlan stripping is no longer needed. In future, the
775 * driver + dpdk will have an API to set the mode after
776 * rte_eal_init. Then, this note and local patch will be
781 * VLAN stripping: default to VLAN strip disabled, unless specified
782 * otherwise in the startup config.
