Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.
