Some networks (such as ours :P ) have semi-broken setups, where both bootp
and dhcp servers are active.  This kind of setup works under Windows, as
Windows will collect all responses from both sets of servers, and use the
union of the answers.  Under pump, though, if the bootp packets (which, due
to bootp limitations, may not have all needed values) happen to get in
first, then dhcp responses will be ignored.  The patch adds the --no-bootp
command line option and a nobootp option in /etc/pump.conf which allows
pump to ignore the bootp responses.  It acts as an effective workaround on
semi-broken setups such as ours.
