Subject: [RFC PATCH] bcm43xx: set channel when the interface is brought up


I have discovered that while I can indeed associate without
wpa_supplicant using bcm43xx_d80211 driver, I have to set the channel
every time the interface is brought down and up.

configuration when the interface is brought up.  I'm not familiar with
d80211 design principles.
