Not because I think it obviates your work, but rather because I'm
curious, could you test a TSO-in-hardware driver converted to
batching and see how TSO alone compares to batching for a pure
TCP workload?

I personally don't think it will help for that case at all as
TSO likely does better job of coalescing the work _and_ reducing
bus traffic as well as work in the TCP stack.
