+ An 802.1Q header contains two important pieces of information: a VLAN
+ ID and a priority. A frame with a zero VLAN ID, called a
+ ``priority-tagged'' frame, is supposed to be treated the same way as
+ a frame without an 802.1Q header at all (except for the priority).
+ </p>
+
+ <p>
+ However, some network elements ignore any frame that has 802.1Q
+ header at all, even when the VLAN ID is zero. Therefore, by default
+ Open vSwitch does not output priority-tagged frames, instead omitting
+ the 802.1Q header entirely if the VLAN ID is zero. Set this key to
+ <code>true</code> to enable priority-tagged frames on a port.
+ </p>
+
+ <p>
+ Regardless of this setting, Open vSwitch omits the 802.1Q header on
+ output if both the VLAN ID and priority would be zero.
+ </p>

+ All frames output to native-tagged ports have a nonzero VLAN ID, so
