### VNET
VNET table has Vnet name as the object key, and vxlan_tunnel name, scope, vni, peer list, advertised prefix, src mac, and overlay dest mac as attributes.
The vxlan_tunnel name (mandatory) is the tunnel name from the VXLAN table. scope (optional) must "default", vni (mandatory) is the vxlan tunnel vni, peer_list (optional) is for Vnet
peering, advertise_prefix (optional) is used to allow advertisement of this vnet's routes, overlay_dmac (optional) is the mac address which is used for VNET ping
monitoring sessions for the vnet routes and is optional.

### VOQ INBAND INTERFACE
VOQ_INBAND_INTERFACE holds the name of the inband system port dedicated for cpu communication. At this time, only inband_type of "port" is supported
