Subject: [Make-wifi-fast] [PATCH] killing retries harder, perhaps

ATH_TXMAXTRY is now unused.
ATH_MAX_SW_RETRIES is insanely high by default.
I finally have some good (well, horrible) data in a consistently noisy
environment and would like to try knocking this down a little in a
future test run. There's smarter ways to do it (like, if you are at
the lowest rate, retry once, higher rates, 4).
I have tried in the past values as low as 2 for soft retries.
