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.

RFC-->v0:
------------
*Rehashed the design to unify RDMA driver. irdma is registered as a
virtbus driver which binds to virtbus devices added
by individual netdev drivers i40e/ice. Listening to netdev notifiers or
running netdev lists are no longer needed for attachment. There is no load
order dependencies between netdev drivers and irdma in the new model.
*Remove asynchronous handling in i40iw_l2param_change() and serialize
l2 param change
*Remove major/minor peer driver ver. checks
*Cleanup QP resources while unwinding from error in irdma_kmode_qp()
itself.
*Remove MAKE_MASK macro
*Separate SQ and RQ work tracker array instead of using a single tracker
array to hold non-uniform objects.
*Remove i40iw driver in current series.
*Use netdev_to_ibdev API to reliably get iwdev in notifiers.
 Remove VSI dev list tracking as a result.
*Fixed build make W=1 issues, sparse endianness warnings, 0-day
 32-bit compile warnings.
*Test for userspaceness with udata and remove uobject references.
*Remove abstractions for memory allocators, dev_* and pr_* prints.
*Remove redundant castings in the driver.
*Relax barriers to a dma_wmb()/dma_rmb() since we are using coherent
 mappings.
*Clang-format run on various portions of the driver.
*Remove internal verb objects tracking from driver as its already done
 in IB core.
*Report correct values for max_send_wr and max_recv_wr in irdma_query_qp()
*Check and fail the call for invalid input values on irdma_create_qp().
*ABI fixups - __aligned_u64 on all u64s. Fix travis hit and removed
 irdma_hw_attrs struct out of ABI.
*Use IRDMA_RING_MOVE_HEAD_NO_CHECK on cq_ring
*Sort call tables, Kconfig, Makefiles
*Add CQ resize feature and few fixes since RFC was published.
*Use same DRIVER_ID enum for irdma as i40iw.
*Updated ib_copy_from_udata/ib_copy_to_udata calls to do a safe copy()
*Adapt to core handling verb object allocations and other core API changes
*devlink is used to switch between RoCE and iWARP on a per function basis
*various driver fixes.
