[net-next,0/9,pull,request] 100GbE Intel Wired LAN Driver Updates 2020-04-17

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.

This series currently builds against net-next tree.

Revision History of RFC submissions
v1: Initial virtual bus submission 
v2: Added example virtbus_dev and virtbus_drv in tools/testing/sefltests/
    to test the virtual bus and provide an example on how to implement
v3: Added ice and i40e driver changes to implement the virtual bus, also
    added the new irdma driver which is the RDMA driver which communicates
    with the ice and i40e drivers
v4: Added other RDMA driver maintainers on the virtbus changes
  * Updated commit message and documentation, removed PM dependency, used
    static inlines where possible, cleaned up deprecated code based on
    feedback for patch 1 of the series
  * Simplified the relationship and ensure that the lifetime rules are
    controlled by the bus in patches 1 & 2 of the series
