Why I did it
Error in socket receiver, causing dhcp6relay to be stuck in infinite while loop when parsing through packet data.
How I did it
Fix recv datatype, add a protection check to check if the next pointer of packet is the same as current pointer.
How to verify it
Which release branch to backport (provide reason below if selected)
