We don't necessarily have a phydev attached when using NC-SI, so it was
easier to have the core code path not have to go fishing for those
settings in different places based on whether we're using NC-SI or not.

Yup but there's little choice. The HW wants it. I don't see any real
point in optimizing that path mind you. Losing a few packets around
a link change isn't going to hurt and it keeps the code a lot simpler
by having a single "re-init" path.

Thanks !

I'll post batch 2 in the next couple of days which tackles the RX path.

Cheers,
Ben.
