Create Multi-Segment Network

Procedure

Create a multi-segment network.

# openstack network create --provider-network-type vlan --provider-segment 333 msnet1

Optional: Create a segment for external connectivity through DC Gateway (DC GW).
```
# openstack network segment create --physical-network EXT_A --segment 333 --network-type vlan –-network msnet1 extseg
```
Regular Virtio ports can be created on a separate segment of the same network.

All corresponding endpoints are provisioned for SR-IOV PF-PT and DC GW after segment creation.
