VF representors are created for each VF when switch mode is set switchdev on representor PCI device
# devlink dev eswitch set pci/0002:1c:00.0  mode switchdev 
# ip link show
25: r0p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 32:0f:0f:f0:60:f1 brd ff:ff:ff:ff:ff:ff
26: r1p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
