New Revision: 218764
URL: http://svn.freebsd.org/changeset/base/218764
Log:
Add in ANI parameters for the AR9280. These aren't enabled by default
as they're likely not entirely correct, but they give people something
to toy with to compare behaviour/performance.
Disable the anti-noise part, as this apparently interferes with
RIFS. I haven't verified this.
