         The parameters are as follows:
 
+ad_select
+
+        Specifies the 802.3ad aggregation selection logic to use.  The
+        possible values and their effects are:
+
+        stable or 0
+
+                The active aggregator is chosen by largest aggregate
+                bandwidth.
+
+                Reselection of the active aggregator occurs only when all
+                slaves of the active aggregator are down or the active
+                aggregator has no slaves.
+
+                This is the default value.

+        bandwidth or 1
+
+                The active aggregator is chosen by largest aggregate
+                bandwidth.  Reselection occurs if:
+
+                - A slave is added to or removed from the bond
+
+                - Any slave's link state changes
+
+                - Any slave's 802.3ad association state changes
+
+                - The bond's adminstrative state changes to up
+
+        count or 2
+
+                The active aggregator is chosen by the largest number of
+                ports (slaves).  Reselection occurs as described under the
+                "bandwidth" setting, above.
+
+        The bandwidth and count selection policies permit failover of
+        802.3ad aggregations when partial failure of the active aggregator
+        occurs.  This keeps the aggregator with the highest availability
+        (either in bandwidth or in number of ports) active at all times.
+
+        This option was added in bonding version 3.4.0.

 arp_interval
 
         Specifies the ARP link monitoring frequency in milliseconds.
