[libvirt] [PATCH v2 0/2] don't masquerade local broadcast/multicast packets



Masquerading local broadcast breaks DHCP replies for some clients.
There has been a report about broken local multicast too.
(See references in the patches.)

Testing: build tested the upstream series. Tested the RHEL-6.4.z and
RHEL-7.0 backports with OVMF netboot on virbr0.

Changes between v1 (at
  http://www.redhat.com/archives/libvir-list/2013-May/msg01872.html
) and v2:
- forward-ported to current upstream master (commit 49a5262d).

This includes conflict resolution for:
