[ovs-dev] [PATCH branch-2.12 0/4] OVN: Backport virtual port related fixes.

[Dumitru Ceara]

This series backports the following OVN virtual port related fixes from
upstream OVN master and branch-20.03:
- patch1: update non-virtual port bindings first in an iteration loop to
  avoid generating two SB DB transactions.
- patch2: fix virtual port bindings to allow parents scheduled in the
  same chassis.
- patch3: add NULL check when accessing the "virtual_parent" column for
  virtual port bindings.
- patch4: skip explicitly binding virtual ports to OVS interfaces.

All patches apply cleanly but for patch2 the unit test had to be adjusted
to check for the correct lr_in_arp_resolve table ID.
