What did you do?

I want read/write raw IP packet,but net/ipv4 not support Windows system. So what can I do this on Windows system.
the code can run on Linux

package main

import (
	"fmt"
	"net"

	"golang.org/x/net/ipv4"
)

func main() {
	c, err := net.ListenPacket("ip4:icmp", "0.0.0.0") 
	if err != nil {
		fmt.Println(1,err)
		return
	}
	defer c.Close()
	ipconn, err := ipv4.NewRawConn(c)
	if err != nil {
		fmt.Println(2,err)
		return
	}
	for {
		buf := make([]byte, 1480)
		hdr, payload, controlMessage, err := ipconn.ReadFrom(buf)
		if err != nil {
			fmt.Println(3, err)
			return
		}
		if payload != nil {
			fmt.Println(hdr, controlMessage)
			fmt.Println(payload)
		}
	}
}

What did you expect to see?

catch some data

What did you see instead?

thanks, I get it.
