What version?

In the sources I'm looking at, LPF uses the fallback interface
for unicasts.

This 'fallback interface' is a standard berkeley UDP socket, so
the destination mac address should be determined by the operating
system.

If you're running 3.0.1 or later, I'd like to see the initial
messages logged (or printed to stdout) by dhclient when it starts
up.  In particular if a Socket/fallback is present on its interfaces
list.
