Upstream/downstream traffic marking

Depending on the priority mechanism that is active, upstream and downstream traffic is
marked as described in this section.

Upstream traffic marking

This table describes the marking applied to wireless traffic sent by connected client stations
to the AP and then forwarded onto the wired network by the AP.

and then sent to connected wireless client stations.
