While not particularly related but a good example:  if we would
provide a better library KPI we could possibly even defer
(pseudo-header) checksum calculations to drivers, which expect
different calculations already anyway, and even save these cycles
on loop as well.

Something more to ponder along with other factoring out of drivers etc.
