Woaw that was fast ! I'll review and give it a test on my setup then.

Maybe one thing to clarify with the net maintainers is that this work
you've done doesn't replace the series this thread is replying to,
which still makes sense (we need the
stmmac_priv->phylink_config.supported_interfaces to be correctly
populated on socfpga).

Thanks a lot for that work Russell,

Maxime

Thanks a lot,

Maxime
