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 and the new RDMA driver 'irdma' for use with 'ice' and 'i40e'.

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 last 16 patches of the series adds a unified Intel Ethernet Protocol
driver for RDMA that supports a new network device E810 (iWARP and
RoCEv2 capable) and the existing X722 iWARP device.  The driver
architecture provides the extensibility for future generations of Intel
hardware supporting RDMA.

Patches 7-25 adds a unified Intel Ethernet Protocol driver for RDMA that
supports a new network device E810 (iWARP and RoCEv2 capable) and the
existing X722 iWARP device.  The driver architecture provides the
extensibility for future generations of Intel hardware supporting RDMA.

The 'irdma' driver replaces the legacy X722 driver i40iw and extends the
ABI already defined for i40iw.  It is backward compatible with legacy
X722 rdma-core provider (libi40iw).

This series currently builds against net-next tree AND the rdma "for-next"
branch.

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
    irdma driver changes:
    * Remove redundant explicit casts
    * Scrub all WQs to define correct charateristics and use system WQ for
      reset recovery work
    * Remove all non-functional NULL checks on IDC peer dev OPs
    * Change all pr_* to dev_* if struct device present. Remove dev_info logging
    * Don't use test_bit on non-atomic IIDC_* event types
    * Remove all module parameters
    * Use bool bitfields in structures instead of bool
    * Change CQP completion handling from kthread to WQ
    * Use the generic devlink parameter enable_roce instead of driver specific
      one
    * Use meaningful labels for goto unwind
    * Use new RDMA mmap API
    * Use refcount_t APIs for refcounts on driver objects
    * Add support for ibdev OP dealloc_driver
    * Adapt to use new version of virtbus
    * Remove RCU locking in CM address resolve
    * Misc. driver fixes

For ease of review and testing, the entire series is available in the
git repository below.
