[j-nsp] IPv4 BFD flaps on MX204

[Ivan Malyarchuk]

If you have many uncontrolled directly connected L2 domains like IX-es or customers, check policer __default_arp_policer__.
If there are drops, you need to apply interface-specific arp policers to interfaces with protocols and/or to source of arp bursts.
