This patch adds support for a new BFD session down message from zebra to
protocols. BGP and OSPF are integrated to respond this BFD session down message
originated in Zebra via ptmd.
BGP and OSPF now have a bfd command, which tells OSPF/BGP to respond to the
BFD session down message.
OSPF:
interface <>
ip ospf bfd
BGP:
router bgp <>
neighbor <> bfd
Please note that these commands don't enable BFD as a protocol. BFD configuration
and paramter tuning are via BFD applicable UI.
