>
> VEB switching feature for i40e is used to enable the switching between the
> VSIs connect to the virtual bridge. The old implementation is setting the
> virtual bridge mode as VEPA which is port aggregation. Enable the switching
> ability by setting the loop back mode for the specific VSIs which connect to PF
> or VFs.
>
> VEB/VSI/VEPA are concepts not specific to the i40e HW, the concepts are
> from 802.1qbg spec IEEE EVB tutorial:
> http://www.ieee802.org/802_tutorials/2009-11/evb-tutorial-draft-
> 20091116_v09.pdf
>
> VEB: a virtual switch can forward the packet based on the specific match field.
> VSI: a virtual interface connect between the VEB/VEPA and virtual machine.
> VEPA: a virtual Ethernet port aggregator will upstream the packets from VSI
> to the LAN port.
