Unfortunately this isn’t a one-liner in Go, as the value 0 is hardcoded for the protocol argument passed in to the socket function.
It should be possible with a raw socket and making the UDP packet myself (not hard), but that requires either root privileges or cap_net_raw and looking at all proto 136 packets, which I don’t love. I’m still asking around and either way I’ll get it done at some point or another. Maybe the Go team would take a patch to add “udplite” as a new “network” argument, but I doubt it, as OS support is limited pretty much to Linux and FreeBSD.
