Format gopacket.Packet network packets similar to the tcpdump CLI output

example

package pktdump_test

import (
	"fmt"

	"github.com/google/gopacket"
	"github.com/google/gopacket/layers"

	"github.com/x-way/pktdump"
)

func ExampleFormat() {
	raw := []byte{0x45, 0x00, 0x00, 0x42, 0x9a, 0x66, 0x00, 0x00, 0x40, 0x11, 0xce, 0xc0, 0xc0, 0xa8, 0x48, 0x32, 0xc0, 0xa8, 0x48, 0x01, 0xfb, 0x6a, 0x00, 0x35, 0x00, 0x2e, 0x02, 0xeb, 0x29, 0x84, 0x01, 0x20, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x06, 0x73, 0x69, 0x67, 0x69, 0x6e, 0x74, 0x02, 0x63, 0x68, 0x00, 0x00, 0x01, 0x00, 0x03, 0x00, 0x00, 0x29, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}

	packet := gopacket.NewPacket(raw, layers.LayerTypeIPv4, gopacket.Default)

	fmt.Println(pktdump.Format(packet))
}

This would produce the following result

IP 192.168.72.50.64362 > 192.168.72.1.53: 10628+ [1au] A CH? sigint.ch. (38)
