Dear mailing list,

I would like to manage the VLAN priority in Wireless QOS (WMM).

I get the VLAN tag from skb->vlan_tci and I extract the VLAN priority. 

How I should handle the priority value 0. 
	- Handle this value as no priority request, In this case the frame will 
		sent with the DSCP priority or default (Best effort)
        - Handle this value as a lowest priority, in this case I Map it to the WMM.

[...]

IEEE 802.1q refers to the definition in 802.1d:

The user_priority parameter is the priority requested by the
originating service user. The value of this parameter is in the range
0 through 7.

NOTE—The default user_priority value is 0. Values 1 through 7 form an
ordered sequence of user_priorities, with 1 being the lowest value and
7 the highest. See 7.7.3 and Annex G (informative) for further
explanation of the use of user_priority values.

So a value of 0 should be treated as no priority request, same as for an
untagged frame.

Ben.
