[spp] [PATCH v3 12/12] spp_vf, spp_mirror: exclude vhosts at process initialization

[Itsuro Oda]

A vhost device is shared among the primary process and secondary
processes. When a secodary process starts it recognizes vhost
devices if they are used by processes already started. It is not
appropriate to include to port information as PHY devices.
