It's quite normal because your controller *is* fast ethernet. You
can't establish a gigabit link.

Hmm, AR8132 uses F1 gigabit PHY but Atheros changed its internal
circuit such that it operates as 10/100 PHY. I guess it's more
appropriate to disable advertisement of 1000baseT capability for
AR8132 case. Would you try attached patch?
In "ifconfig -m alc0" output you should not see 1000baseT
capability.

I don't see any problems from output above.
