+Subject: [PATCH] enic: Set PKT_RX_VLAN_PKT iff returned packet has VLAN tag
+
+Only set the ol_flags PKT_RX_VLAN_PKT bit if the packet being passed
+to the application contains a VLAN tag. This is true whether
+stripping is enabled or disabled.
+
+This area of the API is in flux, so behaviour may change in the
+future.
