Subject: [PATCH net-next 1/4] net: mvneta: Use struct tc_mqprio_qopt_offload for MQPrio configuration

The struct tc_mqprio_qopt_offload is a container for struct tc_mqprio_qopt,
that allows passing extra parameters, such as traffic shaping. This commit
converts the current mqprio code to that new struct.
