This patch introduces the models, the DB migrations and the config options required by the L2 layer to support DVR east/west traffic. These changes will be used by the control-plane made of ML2, L2pop and L2 agent. Two new configuration options have been introduced: 'dvr_base_mac' is used to set DVR MAC addresses apart from tenant ones (every distributed router will have ports being created on compute hosts) and 'enable_distributed_routing' is used to enable dvr support in the L2 agent. This gives the capability of rolling out the dvr functionality in stages. Partially-implements: blueprint neutron-ovs-dvr DocImpact Change-Id: Iab6505f239d2c4c9bcbf4e32a292d7b4b5320c8e Authored-by: Vivekanandan Narasimhan <vivekanandan.narasimhan@hp.com> Co-Authored-By: Armando Migliaccio <armamig@gmail.com>
