[PATCH] bcm43xx: Fix 802.11b/g scan limits to match regulatory reqs
In 802.11b/g mode, bcm43xx actively scans channels 1-14 no matter what locale has been set, either in the sprom or by the locale option. This behaviorviolates regulatory rules everywhere in the world except Japan. This patch changes the default range to the correct value if the locale has been set, and to channels 1-13 if no locale has been set.
