Hi Qian,
Please separated this patch for those three test plans have no relations to each other.

> +==========================
> +

> tutorial-draft-20091116_v09.pdf
> +
> +Virtual Ethernet Bridge (VEB) - This is an IEEE EVB term. A VEB is a
> VLAN Bridge internal to Fortville that bridges the traffic of multiple
> VSIs over an internal virtual network.
> +
> +Virtual Ethernet Port Aggregator (VEPA) - This is an IEEE EVB term. A
> VEPA multiplexes the traffic of one or more VSIs onto a single Fortville
> Ethernet port. The biggest difference between a VEB and a VEPA is that a
> VEB can switch packets internally between VSIs, whereas a VEPA cannot.
> +
> +Virtual Station Interface (VSI) - This is an IEEE EVB term that defines
> the properties of a virtual machine's (or a physical machine's)
> connection to the network. Each downstream v-port on a Fortville VEB or
> VEPA defines a VSI. A standards-based definition of VSI properties
> enables network management tools to perform virtual machine migration and
> associated network re-configuration in a vendor-neutral manner.
> +
> +My understanding of VEB is that it's an in-NIC switch(MAC/VLAN), and it
> can support VF->VF, PF->VF, VF->PF packet forwarding according to the NIC
> internal switch. It's similar as Niantic's SRIOV switch.
> +
> +Floating VEB Introduction
> +=========================
> +
> +Floating VEB is based on VEB Switching. It will address 2 problems:
> +
> +Dependency on PF: When the physical port is link down, the functionality
> of the VEB/VEPA will not work normally. Even only data forwarding between
> the VF is required, one PF port will be wasted to create the related VEB.
> +
> +Ensure all the traffic from VF can only forwarding within the VFs
> connect to the floating VEB, cannot forward out of the NIC port.
> +
> +Prerequisites for VEB testing
