And as we can expect from ASUS, the LED settings are wrong, too. (All are @
0xFF.) The same is true for the antenna bitfields (it has 1 antenna for B/G,
and no A antennas, yet the bitfield says 0 B/G antennas and 2 A ones...).
ASUS has done a terrible work with the SPROM (or perhaps these are the
default values of the SPROM that Broadcom programmed into the chips before
they reached ASUS - who only changed the subsys IDs). The workaround is to
always enable the LEDs for ASUS cards, while the real fix is up to ASUS - it
would be firing the current engineer (who doesn't seem to know the word
"SPROM" and connects Bluetooth GPIO lines to 802.11 TX amplifiers - I
imagine if he was a surgeon, we would have a lot of people who died because
he connected their liver where their heart would have gone...) and getting a
more competent one to do the work. :-)

Apparently it always rounds down, and doesn't follow the 5/4 rule.

Donald, did you have a radiotap interface on the same card while you did
this? I tend to get some dupe pings when I run kismet in the background
(with channel hopping disabled, of course).
