Solarflare X2522 driver info needed?

I`m planning to build an x86 setup and i have an x2522 nic available, and i would like to know if openwrt has drivers for it.
The x2522 has the SFC9250 controller.
There is a package kmod-sfc (SFC9000/SFC9100/EF100-family support), whould this work?

most AMD hardware is natively supported in linux, if openwrt does not support it you have to cross compile it.

can you point me out towards something that explains how to do that?

Install ubuntu ñnd run ethtool eth0
