701 * With Cisco VIC vNIC, every ingress packet is tagged. On a
702 * trunk vNIC (C series "standalone" server), packets on no VLAN
703 * are tagged with vlan 0. On an access vNIC (standalone or B
704 * series "blade" server), packets on the default/native VLAN
705 * are tagged with that vNIC's VLAN. VPP expects these packets
706 * to be untagged, and previously enabled VLAN strip on VIC by
707 * default. But it also broke vlan sub-interfaces.
709 * The VIC adapter has "untag default vlan" ingress VLAN rewrite
710 * mode, which removes tags from these packets. VPP now includes
711 * a local patch for the enic driver to use this untag mode, so
712 * enabling vlan stripping is no longer needed. In future, the
713 * driver + dpdk will have an API to set the mode after
714 * rte_eal_init. Then, this note and local patch will be
719 * VLAN stripping: default to VLAN strip disabled, unless specified
720 * otherwise in the startup config.
