[net-next,v3,0/9,pull,request] 100GbE Intel Wired LAN Driver Updates 2020-05-05

This series contains the initial implementation of the Virtual Bus,
virtbus_device, virtbus_driver, updates to 'ice' and 'i40e' to use the new
Virtual Bus.

The primary purpose of the Virtual bus is to put devices on it and hook the
devices up to drivers.  This will allow drivers, like the RDMA drivers, to
hook up to devices via this Virtual bus.

The associated irdma driver designed to use this new interface, is still
in RFC currently and was sent in a separate series.  A new RFC version
is expected later this week.

This series currently builds against net-next tree.

Revision history:
v2: Made changes based on community feedback, like Pierre-Louis's and
    Jason's comments to update virtual bus interface.
v3: Updated the virtual bus interface based on feedback from Jason and
    Greg KH.  Also updated the initial ice driver patch to handle the
    virtual bus changes and changes requested by Jason and Greg KH.

The following are changes since commit f989d546a2d5a9f001f6f8be49d98c10ab9b1897:
  erspan: Add type I version 0 support.
