From: "Shiraz, Saleem" <shiraz.saleem@xxxxxxxxx> The following patch series introduces a unified Intel Ethernet Protocol Driver for RDMA (irdma) for the X722 iWARP device and a new E810 device which supports iWARP and RoCEv2. The irdma driver replaces the legacy i40iw driver for X722 and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw). X722 and E810 are PCI network devices that are RDMA capable. The RDMA block of this parent device is represented via an auxiliary device exported to 'irdma' using the core auxiliary bus infrastructure recently added for 5.11 kernel. The parent PCI netdev drivers 'i40e' and 'ice' register auxiliary RDMA devices with private data/ops encapsulated that bind to an 'irdma' auxiliary driver. This series is a follow on to an RFC series [1]. This series was built against rdma for-next and currently includes the netdev patches for ease of review. This include updates to 'ice' driver to provide RDMA support and converts 'i40e' driver to use the auxiliary bus infrastructure . Once the patches are closer to merging, this series will be split into a netdev-next and rdma-next patch series targeted at their respective subsystems with Patch #1 and Patch #5 included in both. This is the shared header file that will allow each series to independently compile.
