Check hopcount is correctly incremented by 1 

Extract RFC3315 about hop-count : 
20.1.2. Relaying a Message from a Relay Agent 

   If the message received by the relay agent is a Relay-forward message 
   and the hop-count in the message is greater than or equal to 
   HOP_COUNT_LIMIT, the relay agent discards the received message. 

   The relay agent copies the source address from the IP datagram in 
   which the message was received from the client into the peer-address 
   field in the Relay-forward message and sets the hop-count field to 
   the value of the hop-count field in the received message incremented 
   by 1.
