We can not call any host command that change active channel during scanning. Actually we do cancel scan if config callback was called during scanning. So if a user tried to change channel while scanning this patch will delay the channel change until scan finish, this is the same behavior as sw scan.

Trying to sneak patches past me? ;) Also, I thought you explicitly wanted the channel change callback to be allowed during hw scan because hw scan could return to the home channel inbetween... johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
