This patch begins the work to getting mesh mode working with ath9k. I am
using the b43 and rt2x00 drivers as templates on how to do this.
Unfortunately it doesn't seem to work yet. In attempting to set up a mesh between
an ath9k device and a b43 device, the ath9k device does not seem to be enabling
beaconing. I have a third device in monitor mode that sees the b43 beacons,
sees ath9k responding to them (I believe trying to establish a link), and b43
is acknowledging those responses, but no link is established. On the same ath9k
device, I'm not seeing beaconing in ad-hoc mode, which leads me to believe that
beaconing may be broken right now for my Atheros device. What am I doing wrong?

I would also look at the ath5k driver as (last time I looked) it is
quite similar to ath9k in how mesh beacons would be handled and the RX
filter configuration code is nearly identical.
