Thanks.  The article deals with accepting on a TCP socket, not
receiving on a UDP socket.

But if the principles are similar for UDP, then, as I expected, it
looks like SO_REUSEPORT provides load balancing.

Does anyone believe that dnsmasq is intending to create load balancing
when multiple instances bind to the same DHCP socket?  (I don't.  I
believe dnsmasq is expecting mirroring, but I could be wrong.)
