compat-2.6: ath9k driver

I just got a new HP dv5z laptop with a/b/g/n wifi adapter; it claims to be an AR5009. Googling for the PCI ID (0x002a) matched it up with AR9280, which led me to the ath9k driver. It's not currently provided with the compat-2.6 tree but I pulled a copy from the wireless-testing branch and added it to my compat tree.

It needed 3-4 definitions to be added to <linux/list.h> but otherwise compiled OK and it's now working fine for me in 2.6.26.3. Did you already have plans to include this driver, should I post my diffs?

This patch enables building the wireless-testing ath9k driver with the compat-wireless tarball at http://www.orbit-lab.org/kernel/compat-wireless-2.6/2008/08/compat-wireless-2008-08-06.tar.bz2

In addition to applying this patch, you must also copy the drivers/net/wireless/ath9k directory from the wireless-testing image into the compat-wireless tree. Just posting this for posterity since it seems that it won't be needed for much longer.

Thanks. We can fork wireless-testing for old kernels based on this for compat-wireless. Problem is updates. I suppose each driver maintainer can supply updates when they want. For that please use compat-masters list.

I'll create a new tree for this when I get a chance. The list.h changes should have what we have in the kernel. Although list_splice2() is functionally equivalent I rather use what the kernel is using the name will be different though of course.
