It's replaced by carl9170, which is listed on the same page.  I'll try 
to update the information on that page to make it more obvious for those 
who look specifically for ar9170.

Then I think AR9271 (driver ath9k_htc) is the best option for you. 
Unlike carl9170, it's supported by Atheros.

I think you should ask in Linux-wireless about the hardware and the 
drivers.  wpa_supplicant does its job really well, and it's mostly 
hardware-independent.
