Yep - it comes from the poor integration of phylink into DSA for CPU
and inter-DSA ports which is already causing regressions in today's
kernels. That needs resolving somehow before this patch series can
be merged, but it isn't something that can be fixed from the phylink
side of things.

I'll postpone these patches until that issue is resolved.
