Add unified Intel Ethernet RDMA driver (irdma)

From: "Saleem, Shiraz" <shiraz.saleem@intel.com> This patchset adds a unified Intel Ethernet RDMA driver 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. The underlying LAN driver for X722 ("i40e") and E810 ("ice") have their own peer/client interface that this unified RDMA driver registers to. The netdev_priv structure of each LAN driver accessed by the netdev_priv() interface exposes their peer register/unregister function pointers for use by the RDMA driver. This solution revives an earlier submission [1] intended for a different purpose. It now serves to unify the RDMA driver and we are requesting feedback. The unified driver is currently being tested on X722 with rdma-core-v22. X722 is supported by this driver, but only if CONFIG_INFINIBAND_I40IW is disabled in the kernel. We desire to deprecate or phase out i40iw from the kernel and can submit patches to do the same. We would like to move forward with this unified driver model for current and future HW. This series was built against rdma-next. commit a2bfd708b17a ("RDMA/iwpm: move kdoc comments to functions") It includes both net and rdma patches for the purposes of review. It will be split into two separate patch series, one for net-next and rdma-next once RFC is accepted.
