Are you planning to submit a MQPRIO patch? If not, shall I just wait for your CBS patch to land, and then rebase my AVB patch series on top of net-next?

No, I don't have changes to support MQPRIO in the driver.  I use the
default FPri/Qpri mappings at the moment.

My use case is both: forwarding AVB traffic by the switch, but also
sending traffic from the host at a certain priority.
