Thanks for your patch!

Note that this patch has a hard dependency on "[PATCH v5 1/2] m68k:
io_mm.h - add APNE 100 MBit support" in the series, so it must not
be applied to the netdev tree yet.

According to the recent discussion about that, "at runtime" is not
really possible?  So that limits it to kernel command line (for the
builtin case)
or module parameter (for the modular case).
