- * series "blade" server), packets on the default/native VLAN

- *
- * 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
