-        4. check VM can ping new network DHCP port

+        Neutron security groups always apply anti-spoof rules on the VMs. This
+        allows traffic to originate and terminate at the VM as expected, but
+        prevents traffic to pass through the VM. Anti-spoof rules are not
+        required in cases where the VM routes traffic through it.
+
+        The test steps are :
+        1. Create a new network.
+        2. Connect (hotplug) the VM to a new network.
+        3. Check the VM can ping the DHCP interface of this network.
+        4. Spoof the mac address of the new VM interface.
+        5. Check the Security Group enforces mac spoofing and blocks pings via
+           spoofed interface (VM cannot ping the DHCP interface).
+        6. Disable port-security of the spoofed port- set the flag to false.
+        7. Retest 3rd step and check that the Security Group allows pings via
+        the spoofed interface.
