Hello,

Christian - thanks for the pointer to the function that sets the keys
on the AR9170. I am still figuring out how to use 64 clients with h/w
encryption on the AR9170 - enabling debug/tracing in my build isn't as
straightforward as suggested by the wiki.

However, I did find some very helpful information in the debug files
in 'debugfs' including the number of retries.
The current value is 4 for long packets and 7 for short packets.

I think the small # of retries for regular data packets may be one
reason why I am seeing some throughput problems at longer ranges.

How do I change the number of retries for long packets? Is this a
build-time configuration or can I change it at run-time?

Thanks,
- Harshal
