I'm "only" a Linuy user and not a developer. So I need help to compile / get a netcard driver for an Atheros AR8161 chip for SLES11 SP3.

I've tried to compile different version of backport sources and also the sources from the "alx standalone development tree" https://github.com/erikarn/alx .
I get always a lot of error about "redefinition of xxxx" .

The kernel version is 3.0.76-0.11 default #1 SMP x86_64 from Jun 14 2013 ( ccab990) .
Kernel sources, sym etc installed.

The Atheros chip version is:

AR8161 Gigabit Ethernet [1969:1091] (rev 10)

Any ideas ?
