From: "Shiraz, Saleem" <shiraz.saleem@intel.com>

This patchset 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 HW
supporting RDMA.

This 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 was built against the rdma for-next branch.

v4-->v5:
*Drop driver_data usage from virtbus device id. Use string id
match to identify virtbus device type.
*Rename device discovery functions
*Drop rdma_set_device_sysfs_group API usage
*READ_ONCE annotations for netdev flags in rcu_read_lock 

v4:
*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
*Dont 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
