Current port flavours cover simple switches and DSA.  Add PF
and VF flavours to cover "switchdev" SR-IOV NICs.

Example devlink user space output:

$ devlink port
pci/0000:82:00.0/0: type eth netdev p4p1 flavour physical
pci/0000:82:00.0/10000: type eth netdev eth0 flavour pcie_pf pf 0
pci/0000:82:00.0/10001: type eth netdev eth1 flavour pcie_vf pf 0 vf 0
pci/0000:82:00.0/10002: type eth netdev eth2 flavour pcie_vf pf 0 vf 1  

Wait a second, howcome pf and vfs have the same PCI address?  

Oh, I think you have these as eswitch port representors. Confusing...

FWIW I don't like the word representor, its a port. We don't call
physical ports "representors" even though from ASIC's point of view
they are exactly the same.
