ieee80211_hw_config() is called from scanning functions and ioctl
handlers, but not when the interface is brought up. This is
unreasonable. Since the config function is provided by hardware drivers
to d80211, the later should be responsible for calling it in all
situations when the hardware needs to be reconfigured.
Without this patch, bcm43xx_d80211 needs the channel to be set again
after the interface goes down and up. Similar problems are reported for
rt2x00 drivers.
Failure in ieee80211_hw_config() leads to the interface staying down.
