Either way, bypassing the bridge has mixed results: latency improves
but throughput takes a hit (no GRO).  

Well, for some traffic mixes XDP should be able to keep up without GRO.
And longer term, we probably want to support GRO with XDP anyway

Do you have any numbers to back up your expected throughput decrease,
due to lack of GRO?  Or is it a theory?

of course. I'll start a new thread about this rather than go too far
down this tangent relative to the current patches.
