The 8000 series and newer NICs all get hardware timestamps from the MAC
and can provide timestamps on a normal TX queue, rather than via a slow
path through the MC. As such we can use this path for any packet where a
hardware timestamp is requested.
This also enables support for PTP over transports other than IPv4+UDP.
