Before reviewing this patch (with many outcomes at first glance),
we need experimental data, eg how this is expected to work on a
typical host with 100Gbit NIC (multi queue), 64 cores at least,
and what is the performance we can get from it (Number of skbs per second,
on a class limited to 99Gbit)

Four lines of changelog seems terse to me.
