+ * 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
