AFAICS, it should work, but it does not look the most suitable to me:
beyond splitting a "simple" task in separate entities, it poses a
constraint on the classification performed on the egress device.

Suppose the admin wants to limit the egress bandwidth on the given tx
queue _and_ do some application specific packet classification and
actions. That would not be possible right?

Thanks!
