From ec891c8b8da2c3862a5f76ba72f6d140c418d812 Mon Sep 17 00:00:00 2001 From: Mahesh Bandewar Date: Wed, 8 Mar 2017 10:55:59 -0800 Subject: [PATCH] bonding: remove "port-moved" state that was never implemented LACP state-machine defines "port-moved" state when the same ActorSystemID and Port are seen in a LACPDU received on different port. The state is never set since it's not implemented. However the state-machine attempts to clear that state occasionally. LACP state machine is already complicated and since this state is not implemented, removing it's checks makes the state-machine little simpler. Signed-off-by: Mahesh Bandewar Signed-off-by: David S.
