LGTM, pending the MSTOP() part.
Is the MSTOP() handling needed to function? IIUIC, all modules are
enabled
out of reset.
If it is not needed, I can take this patch and remove the MSTOP() part.

MSTOP is not needed for Ethernet to work. Indeed, all modules are enabled
out of reset.

It's OK for me. Thank you for handling this.
Anyway, let me know if you encounter issues with it so I can resend it.
Thank you,
