Degradation in performance
Degradation in performance indicates that openvswitch may not be offloaded.
Verify offload state. Run:
            
            # ovs-vsctl get Open_vSwitch . other_config:hw-offload
    
- If hw-offload = true – Fast Pass is configured (desired result) 
- If hw-offload = false – Slow Pass is configured 
If hw-offload = false :
- For RHEL/CentOS, run: - # ovs-vsctl set Open_vSwitch . other_config:hw-offload=true; # systemctl restart openvswitch; # systemctl enable openvswitch; 
- Ubuntu/Debian: - # ovs-vsctl set Open_vSwitch . other_config:hw-offload=true; # /etc/init.d/openvswitch-switch restart
