Subject: 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.
