packete regalo

To finish it off we create another packet but actually fill in some regalo MAC addresses for navidad the ethernet layer, some IP addresses for IPv4, and port numbers for the TCP layer.
It is also useful if you want to create your own l33t protocol that does not even use TCP/IP or ethernet.
Just place your packet dump in the box above and hit 'Decode Packet'.

Intro, the gopacket package provides a, go wrapper for libpcap written.
The layers package is something new in the Go library that is not available in the underlying pcap library.
The authors of gopacket took the time to create types regalo for many known layers like ethernet, IP, UDP and TCP.
