TPC has been supported for a long time.  DFS can be implemented w/o the
hal blindly interfering.  Talk to the madwifi folks about why having the
hal try to do radar processing is bad; they suffered through the one hal
release Atheros made (note Atheros, not me) where there was an attempt
at detecting radar for the purpose of implementing DFS.

If you read my original commit msg it clearly states I am removing stub
code.  If you want to complain that Atheros isn't giving away a
radar/DFS implementation then talk to them.  But be sure to show up with
a list of vendors that: a) currently do so, or b) provide sufficient
information about their hardware that you can implement it yourself.  I
figure if you can supply either they will immediately provide code--if
it's even possible.
