+/**
+ * Enable dedicated hw queues for 802.3ad control plane traffic on on slaves
+ *
+ * This function creates an additional tx and rx queue on each slave for
+ * dedicated 802.3ad control plane traffic . A flow filtering rule is
+ * programmed on each slave to redirect all LACP slow packets to that rx queue
+ * for processing in the LACP state machine, this removes the need to filter
+ * these packets in the bonded devices data path. The additional tx queue is
+ * used to enable the LACP state machine to enqueue LACP packets directly to
+ * slave hw independently of the bonded devices data path.
+ *
+ * To use this feature all slaves must support the programming of the flow
+ * filter rule required for rx and have enough queues that one rx and tx queue
+ * can be reserved for the LACP state machines control packets.
+ *
+ * Bonding port must be stopped to change this configuration.
+ *
+ * @param port_id      Bonding device id
