The lacp_slave_is_current() function is used to indicate to a controller failover status of the LACP module. However, the result of this function is more strict than the failover logic. Thus, the function will generally return false quite a bit before a failover actually happens. This patch loosens lacp_slave_is_current() so that it changes in-line with the failover logic.
