Hello everyone,
I would like add a support for ASUS RT-N65U. There was an similar thread, but just an request without any technical details. So I decided to do it by own.
Here are the results:

- RTL8367B switch is not detected. Looks like, that something is wrong with MDIO bus, while it can't detect the switch. Not sure if
3883-socis able to handle with MDIO and not via GPIO. So how to get it working?

The main problem which I have is, that I don't have any kind of schematic. Basically everything is based on other devices and technical data which I found.
Current status could be found here.
Any kind of help is welcome.
