Subject: Alx driver doesn't work on 3.7.x

Hello,
I don't know wheter it is the right place for it but I want to report
a bug(I think it is).
I'm a Asus N56VZ user with ArchLinux on it. It has an Atheros AR8161 ,
so I use alx driver. It was working with 3.6 series kernel but now
with 3.7.3 and
3.7.4 it stopped working. I was upgraded compat driver version
2012-12-19 to use alx with 3.7 series. When It generated errors I
tried also compat 3.7.1
and 2013-01-10-2u. Also tried a solution which says comment some lines
on 3.6.8-snpc (which is given in
http://www.linuxfoundation.org/collaborate/workgroups/networking/alx).
The first two caused same error below when I got ip connection both
with NetworkManager and ifconfig. The last solution wih 3.6.8 worked
but connection
drops always after a while.

The output of dmesg when I connected:
