Atheros DFS radar detection

[Adrian Chadd]

.. basically, let's establish that you're using a sane/sensible set of
parameters before we go off and try to see why you're seeing such high
false detects.

It's expected that you'll see quite a few false detects on the AR5212
era NICs, but I don't recall it being quite that bad in my limited
testing.

So for madwifi-dfs, it'd be here:

http://madwifi-project.org/browser/madwifi/branches/madwifi-dfs/ath/if_ath_radar.h

Tell me what the value of register 0x9954 is.

Are you running the madwifi-dfs code on FreeBSD somehow? Or are you
actually doing this with madwifi? It'd be cool if you could bring this
up on FreeBSD, as I'm happy to work with the community if they're
willing to take charge of porting over the madwifi-dfs pattern
matching code and work on false detection avoidance.

2c,
