   ## Summary
   
   We don't reply ICMP error message when the destination address is broadcast/multicast.
   
   According to rfc1112, section 7.2:
   "An ICMP error message (Destination Unreachable, Time Exceeded, Parameter Problem, Source Quench, or Redirect) is never generated in response to a datagram destined to an IP host group."
   
   ## Impact
   
   Response to udp broadcast and multicast.
   
   ## Testing
   Local packet capture verification.
