StdNetBind implements Bind for all platforms. While Windows has its own Bind (see bind_windows.go), it may fall back to StdNetBind. TODO: Remove usage of ipv{4,6}.PacketConn when net.UDPConn has comparable methods for sending and receiving multiple datagrams per-syscall. See the proposal in https://
