"This revision adds the following new features:
- ingress/egress ACLs support
- moved ACL definitions to vpp-acl module
- updated l2 container constraint (permit IP address on BVI interface)
- added PID of vpp process to vpp-state
- added support for Loopback interfaces
- added support for port mirroring";
