It looks like the original patch didn't appear in patchwork for some
reason - at least google can find it in lore's netdev archives, but
not in patchwork. I can only put this down to some kernel.org
unreliability - we've seen this unreliability in the past with netdev,
and it seems to be an ongoing issue.

It's now too late to re-send for this merge window - net-next is
currently closed. Whether I remember in a fortnight or so time when
net-next re-opens is another problem.

And yes, I also have the phylink_set_10g() patches in my tree, which
was waiting for this patch to have been merged.
