Hi Andrew,

Does it make a difference if you do it by hand? Bring up the master
interface, wan, lan0, lan1, add any bridge you need, etc.
From power on, none of the wan, lan0, lan1 or br0 achieve link
(LOWER_UP).
I can explore this but I don't know at the moment. I believe that all
interfaces are configured.
In serdes.c, interrupts are used to monitor link changes. However,
phy.c doesn't do this and
it doesn't call phylink_mac_change().
Is the master interface up? What does ip link show give?
The master interface (eth0 on mvneta) always comes up. The link status
of this interface
appears to be checked by polling at 1 second intervals.
After a power on boot, this is what I see:
