The problem I faced was because the message is sent only once _before_
timeout starts ticking, so no matter what it's set to, the message
wouldn't be there.

Documentation  says "Wait (with a packet sniffer) for a special
broadcast packet and press a button". So I think with this patch
documentation changes are not strictly necessary, it still works the
same way, you wait for the packet and press a button.

Currently all devices wait for 2 seconds during normal bootup no
matter what. Without my patch any value for that timeout wouldn't help
with the UDP message.
