[OpenWrt-Devel] ar8216: phy_init and bug report 18415

Sun Jan 25 13:05:52 EST 2015

To me it doesn't look like an issue with the AR8216 driver. All related output is ok.
The hardware is quite common and in case of a driver issue I would expect much more
people to complain.

What looks a little strange to me is that there seem to be two interfaces (modem + wan)
fiddling with eth0.2
