>Slow path means allowing packet to go from uplink to representor and from
>representor to correct VF on Rx site and from VF to representor and to uplink
>on Tx site.

>To acomplish this driver, has to set correct Tx descriptor. When packet is sent
>from representor to VF, destination should be set to VF VSI. When packet is
>sent from uplink port destination should be uplink to bypass switch
>infrastructure and send packet outside.
>
>On Rx site driver should check source VSI field from Rx descriptor and based
>on that forward packed to correct netdev. To allow this there is a target
>netdevs table in control plane VSI struct.
