Hi Allan

Just throwing out another idea....

The whole offloading story has been you use the hardware to accelerate
what the Linux stack can already do.

In this case, you want to accelerate Device Level Ring, DLR.  But i've
not yet seen a software implementation of DLR. Should we really be
considering first adding DLR to the SW bridge? Make it an alternative
to the STP code? Once we have a generic implementation we can then
look at how it can be accelerated using switchdev.
