Specifies an alternate link layer (Layer-2) priority value for packets that do not conform to the flow specification. The Packet Scheduler inserts the corresponding priority value in the Layer-2 header of the packets. If you enable this setting you can change the default priority value associated with nonconforming packets. If you disable this setting the system uses the default priority value of 0. Important: If the Layer-2 priority value for nonconforming packets is specified in the registry for a particular network adapter this setting is ignored when configuring that network adapter.
