- * A note on Cisco VIC (PMD_ENIC) and VLAN:
- *
- * With Cisco VIC vNIC, every ingress packet is tagged. On a
- * trunk vNIC (C series "standalone" server), packets on no VLAN
- * are tagged with vlan 0. On an access vNIC (standalone or B
- * series "blade" server), packets on the default/native VLAN
- * are tagged with that vNIC's VLAN. VPP expects these packets
- * to be untagged, and previously enabled VLAN strip on VIC by
- * default. But it also broke vlan sub-interfaces.
- *
- * The VIC adapter has "untag default vlan" ingress VLAN rewrite
- * mode, which removes tags from these packets. VPP now includes
- * a local patch for the enic driver to use this untag mode, so
- * enabling vlan stripping is no longer needed. In future, the
- * driver + dpdk will have an API to set the mode after
- * rte_eal_init. Then, this note and local patch will be
- * removed.
