BFD: add ARP-awareness, fix bugs
Make BFD ARP-aware when sending out packets. Fix a few one-liner bugs discovered while integrating with cisco nexus. Enhance CLI view to better observe session state. Change-Id: I266c29492f351207b84328ab665d9d697969da9c Signed-off-by: Klement Sekera <ksekera@cisco.com>
