How FPolicy manages external communication during LIF migration or failover

Data LIFs can be migrated to data ports in the same node or to data ports on a remote node.

When a data LIF fails over or is migrated, a new control channel connection is made to the FPolicy server. FPolicy can then retry SMB and NFS client requests that timed out, with the result that new notifications are sent to the external FPolicy servers. The node rejects FPolicy server responses to original, timed-out SMB and NFS requests.
