+Subject: [PATCH] net/enic: untag default vlan by default
+
+The current default ingress vlan rewrite mode 'passthrough' is not
+suitable for VPP, as it leads to ingress packets tagged with vlan 0
+(trunk-mode vNIC) or native vlan (access-mode vNIC). Change the
+default to "untag default vlan" to remove these unwanted tags.
