+Subject: [PATCH] bonding: 3ad: fix carrier and tx with no active ports
+
+bond carrier state should not be be up when no ports are in
+aggregation. Ports should only be enabled when they are in aggregation.
+
+While in there, set the default template to fast mode to quickly recover
+links and shorten the non-standard aggregator selection timer.
