You are adding eight bytes per frame for what is arguably an extreme
niche case.

I don't think it is a niche case, btw. I was always wondering why
NXP introduced the vclock thingy. And apparently it is for
802.1AS-rev, but one use case for that is 802.1Qbv and there you'll
need a (synchronized) hardware clock to control the gates. So while
we can have multiple time domain support with the vclock, we cannot
use Qbv with them. That was something I have always wondered about.
Or.. maybe I'm missing something here.

Niche is relative.

Believe it or not, the overwhelmingly great majority of people using
Linux have no interest in TSN.

Thanks,
