	Well, I'm certainly not looking for anything pretty.

	Should it not be possible to determine what the TX rate would be
for the associated station and simply set frmhdr.wi_tx_rate to 110 if the
TX rate is 11mbit, otherwise lay off and don't touch it? This wouldn't be
a "perfect fix" by any-means but again, I'm not looking for anything
pretty, just something to get associated stations up to 11mbit when they
can support it.

	It is my understanding that frmhdr.wi_tx_rate, though specified,
is not changed in the driver, thus defaults to 0 which would be 2mbit TX
(and that is exactly what we are seeing).

	Scott
