Since linux-stable 5.10.112 commit:

1ff5359afa5e ("net: micrel: fix KS8851_MLL Kconfig")

it is not possible to select KS8851_MLL symbol.

This is because the commit adds dependency on Kconfig symbol

PTP_1588_CLOCK_OPTIONAL

which was added in Linux upstream commit:

e5f31552674e ("ethernet: fix PTP_1588_CLOCK dependencies")

And the aforementioned commit is not part of stable 5.10.112.

Can you send a commit to revert this?

I can, but I have one question -- should this really be reverted or would it be better to pick the missing dependency, commit:

e5f31552674e ("ethernet: fix PTP_1588_CLOCK dependencies")

It seems the missing dependency is also a fix.
