It is not using AF_PACKET to support some strange probes, it only supports
UDP jitter for Cisco.
It is using AF_PACKET so it can see full header MAC, VLAN, IP, so it can
respond to any IP, any VLAN, without needing explicit configuration in
responder end.

It can be huge OPEX save, when no one needs to be taught how to add VLAN to
linux. When you want to add new IP SLA/RPM for L3 MPLS VPN, you just
configure the PE and leave responder alone. You don't even have to know if
the polling client is Cisco or Juniper.
