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