[PATCH v2 0/5] Fix bug 209

[David Gibson <david@gibson.dropbear.id.au>]

Here are a handful of changes to forwarding ant multicast handling,
that fix bug 209.  It also gets us closer to correct multicast
handling, though we're certainly not there yet - multicast things
currently only really work at all because IP_MULTICAST_ALL defaults to
on, and for the common protocols the host is likely to be already a
group member.

v2:
 * Assorted minor polish based on feedback

David Gibson (5):
  fwd: Clarify semantics of --host-lo-to-ns-lo
  udp: Validate that we have a unicast source address
  fwd: Rework default address logic for inbound flows
  fwd: Reorder DNAPT and SNAT steps in fwd_nat_from_host()
  fwd: Don't rewrite inbound multicast destinations
