In vSphere 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, and let the tagged traffic reach the virtual machines that are associated with VFs, that is, enable Virtual Guest Tagging (VGT).|
