示例1: writeThenReadPayload
// writeThenReadPayload transmits IPv4 datagram payloads to the
// loopback address or interface and captures the loopback'd datagram
// payloads.
func writeThenReadPayload(t *testing.T, i int, c *ipv4.PacketConn, wb []byte, dst net.Addr) []byte {
rb := make([]byte, 1500)
c.SetTOS(i + 1)
var ip net.IP
switch v := dst.(type) {
case *net.UDPAddr:
ip = v.IP
case *net.IPAddr:
ip = v.IP
}
if ip.IsMulticast() {
c.SetMulticastTTL(i + 1)
} else {
