Also, fix a small set of "avail." If we're setting `avail,' we shouldn't
be re-checking whether m_flags is M_EXT, because we know that it is, as if
it wasn't, we would have already returned several lines above.

only be checked if the system is currently performing New Reno style
fast recovery. However, this value was being checked regardless of the
NR state, with the end result being that the congestion window was never
opened.
Change the logic to check t_dupack instead; the only code path that
allows it to be nonzero at this point is NewReno, so if it is nonzero,
we are in fast recovery mode and should not touch the congestion window.

PPTP links are no longer dropped by simple (and inappropriate in this
case) "inactivity timeout" procedure, only when requested through the
control connection.
It is now possible to have multiple PPTP servers running behind NAT.
Just redirect the incoming TCP traffic to port 1723, everything else

this does not affect the behavior of the ISI rsvpd but allows
another rsvp implementation (e.g., KOM rsvp) to take advantage
of the new style for particular sockets while using the old style
for others.
in the future, rsvp supporn should be replaced by more generic
router-alert support.

it should only run if the callout is active and not on the wheel.
