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 1Wait 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.
My point is, they are not PFs and VFs. We have to find a way to clearly see what's what.
