In vSphere 5.5 and later, you can configure certain networking features on a virtual machine adapter that is associated virtual function (VF). Use settings for the switch, for the port group, or for a port depending on the type of the virtual switch (standard or distributed) that handles the traffic.
|MTU size||Change the size of the MTU, for example, to enable jumbo frames.|
|Security policy for VF traffic||
|VLAN tagging mode||Configure VLAN tagging in the standard or distributed switch, that is, enable VLAN Switch Tagging (VST) mode, or let the tagged traffic reach the virtual machines that are associated with VFs, that is, enable Virtual Guest Tagging (VGT).|
