+In cases when interface is used in the L2 mode or promisc mode is needed for some other reason,
+trust needs to be set to "on" using the linux "ip link" utility.

+### L2 spoofing check
+By default Virtual Function is not allowed to send ethernet frames which
+have source MAC address different than address assigned to the VF.
+In some cases it is expected that VPP will send such frames (e.g. L2 bridging,
+bonding, l2 cross-connect) and in such cases spoof chack needs to be turned

 ### Interface Creation
 Interfaces can be dynamically created by using following CLI:
