atheros driver under high load, panics and even more freezes

[Daniel Dvořák]

And there is diffrence even between 

-i 0.002 and 0.0019
0.002 is okay 1,4ms 0,0019 means "no buffers, PL, big latency, OACTIVE flag"

with -f no problem 0% PL and avg latency 1,5 ms and the throughput 0,89MB/s
IN and OUT.

I am sorry for dividing to 3 emails.
