It's usually the arge1 which is dedicated to switch and it's
hard-programmed as 1000/full (even when the switch ports are just 10/100).

arge0 is the 'WAN' port (using the dedicated PHY 4).

The MDIO is at arge0 on ar7240 and at arge1 on ar7241.

Thanks Adrian!

Stefan also has a nice documentation about how this stuff fits together:
