示例1: runPayloadTransponder
// runPayloadTransponder transmits IPv4 datagram payloads to the
// loopback address or interface and captures the loopback'd datagram
// payloads.

cf := ipv4.FlagTTL | ipv4.FlagDst | ipv4.FlagInterface
rb := make([]byte, 1500)
for i, toggle := range []bool{true, false, true} {
