From: Vladimir Oltean <vladimir.olt...@nxp.com>
Even though we should really share the implementation with the ocelot
switchdev driver, that one needs a little bit of rework first, since its
struct ocelot_port_tc only supports one tc matchall action at a time,
which at the moment is used for port policers. Whereas DSA keeps a list
of port-based actions in struct dsa_slave_priv::mall_tc_list, so it is
much more easily extensible. It is too tempting to add the implementation
for the port priority directly in Felix at the moment, which is what we
do.
