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.
