calling ath_update_txpow

[Sam Pierson]

Hi all,

I have been looking at this function in if_ath.c:

static void
ath_update_txpow(struct ath_softc *sc)

Is there an example somewhere of using this function in
a user-space application to control the signal strength?
Up until this point I've just been stringing together system()
calls saying "ifconfig ath0 txpower" and it's very dirty.  I'd like
to be able to actually use the device driver and not ifconfig.
