AR8161 ethernet using compat-wireless

After rooting the kindle being bugging me whole day yesterday, it’s time to deal with Atheros ar8161 ethernet driver. This ethernet chipset were used on axioo komodo model and some asus laptop. Once, I remember have to deal with atheros ethernet chipset in past, not clearly remember the chipset code, but for so long the atheros driver was maintained very well with atl modules in kernel tree.

Here is the long story short,
This is what lspci gives :

No indicated network devices on ubuntu networkmanager neither on net_applet on KLIXs. My first thought, it must be supported on newer kernel and directly gives a shot on oneiric with my 3.2.0-16-jf2-generic and also on KLIXs with my brand new kernel-3.2.15-jf2-bfs … and … it returns nothing ;D … even with my latest build linux-image 3.3.0-994-jf1-generic with intel-drm-fix on ubuntu still cannot fire up the ethernet device.
Whooah … this must be an interesting hardware devices …

Googling around the net found some clue on linux.kernel mailing list … Apparently the new atheros module alx wasn’t accepted yet to kernel tree (maybe because hand over on atheros company … dunno … but my bookmark on atheros repository download page giving 404). The original maintainer handed over the alx driver module to the other guy and the other guy deprecated the old atl1c module. 😀 ;D
But, fortunately, now alx supports these two chipsets additionally :
* 1961:1091 – AR8161
* 1969:1090 – AR8162

You may get the latest compat-wireless from linux wireless download page. Extract them to your like folder and cd into it.

EDIT 062512 :

You may read the below comments since latest compat wireless package was obsoletes the alx driver module.

Here we go, To only compile the needed module alx for ar8161 :

sudo make wlunload to unload wireless modules
sudo make btunload to unload bluetooth modules

Run sudo modprobe driver-name to load your desired driver.
If unsure reboot.
