I'm sorry, that was certainly not intentional and I may have missed
your comments. Actually it doesn't look like they have made it to the
netdev list archive or patchwork either.

I've changed Kconfig stuff according to your recommendation and also
addressed possible misleading USXGMII and 10GBase-KR support by
introducing MT7988-specific functions and using 'internal' PHY mode.
So which of your comments have not been addressed?

I was also surprised the series made it to net-next so quickly, but it
wasn't me applying it, I merly posted v2 with all comments I received
addressed.

Me and supposedly also netdevbpf maintainers use patchwork to track
patches and whether comments have been addressed. Can you point me to
emails with the comments which haven't been addressed there? Looking in
patchwork for the dt-bindings patch [1] I don't see any comments there.


Thank you for reviewing!


Daniel

didn't have the dt-bindings addition, I introduced it with RFCv3 when splitting
the series into many small changes:
