[libvirt] [patch 0/3] Fixes related to the IP address learning thread

[Stefan Berger]

Proper resubmission -- sorry for the noise.

The following set of patches are primarily related to the
thread learning the IP address of a VM and deal with:

- ebtables cleanup before applying basic filtering rules while
  the IP address is detected
- shutting down all traffic in case the filtering rules could
  not be applied by the thread
- serialization of the teardown of eb/ip/ip6tables rules to
  occurr after the IP address learning thread has terminated
- no to apply or tear any eb/ip/ip6tables rules while the
  IP address learning thread is active

Regards,
  Stefan
