-Subject: net: mvneta: Allow having more than one queue per TC
-
-The current mqprio implementation assumed that we are only using one
-queue per TC. Use the offset and count parameters to allow using
-multiple queues per TC. In that case, the controller will use a standard
-round-robin algorithm to pick queues assigned to the same TC, with the
-same priority.
-
-This only applies to VLAN priorities in ingress traffic, each TC
-corresponding to a vlan priority.
