Regression: Network link not coming up after suspend/resume cycle

[Jan Janssen <medhefgo@web.de>]

Hi,

I've been noticing lately that my network link sometimes does not go up
after a suspend resume cycle (roughly 1 or 2 out of 10 times). This also
sometimes happens with a fresh boot too. Doing a manual
"ip link set down/up" cycle resolves this issue.

I was able to bisect it to the commit below (or hope so) and also CCed
the maintainer for my driver too.

This is happening on a up-to-date Arch Linux system with a Intel I219-V.

taprio: make clock reference conversions easier

Later in this series we will need to transform from
CLOCK_MONOTONIC (used in TCP) to the clock reference used in TAPRIO.
