I submitted a set of patches to resolve some of the PS issues in ath9k.
I would expect these to hit wireless-testing.git eventually, but if you
are willing to test the changes before that, you can find the patches
from http://w1.fi/p/ps/

One thing to note here is that there are still some issues with the
timeout=0 case (use of PS-Poll to fetch buffered frames) which is
enabled with "iwconfig wlan0 power on", so at this point, I would
recommend running the test either with the default wireless-testing.git
PS mode setting or by enabling power saving with "iwconfig wlan0 power
timeout 500ms" which should result in the same configuration.

I have not tested these on AR5418, but at least with AR9280, these
patches do improve stability and general functionality of the default PS
mode considerably. I have been able to run multi-hour tests without
losing connection.
