[net-next PATCH 0/3] Retrieve number of VFs in a bus-agnostic way

[Phil Sutter <phil@nwl.cc>]

Previously, it was assumed that only PCI NICs would be capable of having
virtual functions - with my proposed enhancement of dummy NIC driver
implementing (fake) ones for testing purposes, this is no longer true.

Discussion of said patch has led to the suggestion of implementing a
bus-agnostic method for VF count retrieval so rtnetlink could work with
both real VF-capable PCI NICs as well as my dummy modifications without
introducing ugly hacks.

The following series tries to achieve just that by introducing a bus
type callback to retrieve a device's number of VFs, implementing this
callback for PCI bus and finally adjusting rtnetlink to make use of the
generalized infrastructure.

Phil Sutter (3):
  device: bus_type: Introduce num_vf callback
  PCI: implement num_vf bus type callback
  device: Implement a bus agnostic dev_num_vf routine
