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

[Pavel Roskin <proski-mXXj517/zsQ@public.gmane.org>]

Hello!

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.

It turns out d80211 uses the "config" method of the hardware drivers
very sparingly.  It's only used for scanning and in ioctl commands.  It
is not called after the interface has been brought up with the "open"
method.

I don't know whose responsibility it should be to apply the
configuration when the interface is brought up.  I'm not familiar with
d80211 design principles.

If the hardware drivers are supposed to do it, here's my patch.  It is
working fine for me and ready to be applied.  The changelog is in the
subject.
