bug: `tp` (transport header) should only be required if `ip.nw_proto` is TCP (int 6) or UDP (int 17) #83

Closed viniarck closed 4 days ago

If you try to send let's say a ICMP header (protocol number 1), although we don't have a correct fully serialization of ICMP it just set the ip protocol field accordingly (same way as it used to send protocol value 0 with whatever serialization), it shouldn't require a tp layer layer here. The tp transport layer for now is just for TCP (int 6) or UDP (int 17):
