Procedure

In OVSDB, setup the dpdk-extra parameter as in the following example:
```
# ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-extra=”-n6 \
--iova-mode=pa --vfio-vf-token=14d63f20-8445-11ea-8900-1f9ce7d5650d \
-a 0000:3b:00.0 -a 0000:3b:00.4 -a 0000:3b:00.5”
```
This configures 3 ports, the mandatory VF#0 and then additionally VF#4 and VF#5. These are now configured with 1 queue each.
Set --vfio-vf-token to the uuid which is generated using the uuidgen command. For example:
```
uuidgen
14d63f20-8445-11ea-8900-1f9ce7d5650d
```

For a multiqueue setup, add the portqueues[] parameter to VF#0 as in the following example:

# ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-extra=”-n6 \
--iova-mode=pa --vfio-vf-token=14d63f20-8445-11ea-8900-1f9ce7d5650d \
-a 0000:3b:00.0,portqueues=[4:2,5:2] -a 0000:3b:00.4 -a 0000:3b:00.5”

VF#4 with 2 queues and VF#5 with 2 queues is created.

In OVSDB, define OVS representor virtual ports as in this OVS bridge example:

# ovs_vsctl add-port br0 dpdkvp0 – set interface dpdkvp0 \
type=dpdk options:dpdk-devargs=”0000:3b:00.4”
