Ideally, the series should also have the implementation of these hints
for a couple of devices and appropriate selftest updates to exercise
them.
For GSO, CC Willem going forward (I don't think I understand why
we want to have gso_type in the TX hint; something like header_len
seems like a better fit).
Please also don't post v3 yet and allow at least a week for the initial
reviewers to catch up..
