+* **Flow pattern without any specific vlan will match for vlan packets as
well.**
+
+ When VLAN spec is not specified in the pattern, the matching rule will be
created with VLAN as a wild card.
+ Meaning, the flow rule::
+
+ flow create 0 ingress pattern eth / vlan vid is 3 / ipv4 / end ...
+
+ Will only match vlan packets with vid=3. and the flow rules::
+
+ flow create 0 ingress pattern eth / ipv4 / end ...
+
+ Or::
+
+ flow create 0 ingress pattern eth / vlan / ipv4 / end ...
+
+ Will match any ipv4 packet (VLAN included).
