This is confirmed as a regression on the Realtek RTL8211F community driver for kernel 5.4.

RTL8211E used on STM32MP157x-EV1 is not affected.

This is not related to ST work (although we should have discovered this regression), we are checking for a patch or a solution.

I keep you posted if I see progress.
