Creation of virtual function has always been supported. You need to be more specific about the new use case please. > +After enabled, the PF needs the VF token in UUID format to setup the trust > or collaboration between SR-IOV PF and VFs. > +The VFs created are bound to vfio-pci module automatically, and the VF also > needs VF token to gain access to the device. > +DPDK will use the keyword ``vf_token`` as device argument to pass the VF > token value to PF and its related VFs. You need to explain where the token comes from. Can it be any random UUID?
