At least I'm not aware of any such work. Issue with Realtek is that
they answer individual questions very quickly but company policy is
to not release any datasheets or errata documentation.
RTL8169 inherited a lot from RTL8139, so I would expect that the
r8169 driver could be a good basis for a RTL8125 mainline driver.
