Reverting it makes things work again. It seems like phylink_get_inband_type doesn't handle base-R modes at all? I'll maybe have some more time to poke this myself later this week, but throwing it out there in case anyone more experienced has ideas.
10GBASE-CR (based upon BASE-R) has no inband signalling for
autonegotiation.
Please enable debugging in phylink and include this is any bug report.
Thanks.
