Merge branch 'irdma' into rdma.git for-next
Shiraz Saleem says: ==================== Add Intel Ethernet Protocol Driver for RDMA (irdma) 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 module replaces the legacy i40iw module 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 auxiliary drivers registered in irdma module. Currently, default is RoCEv2 for E810. Runtime support for protocol switch to iWARP will be made available via devlink in a future patch. ==================== Link: https://lore.kernel.org/r/20210602205138.889-1-shiraz.saleem@intel.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * branch 'irdma': RDMA/irdma: Update MAINTAINERS file RDMA/irdma: Add irdma Kconfig/Makefile and remove i40iw RDMA/irdma: Add ABI definitions RDMA/irdma: Add dynamic tracing for CM RDMA/irdma: Add miscellaneous utility definitions RDMA/irdma: Add user/kernel shared libraries RDMA/irdma: Add RoCEv2 UD OP support RDMA/irdma: Implement device supported verb APIs RDMA/irdma: Add PBLE resource manager RDMA/irdma: Add connection manager RDMA/irdma: Add QoS definitions RDMA/irdma: Add privileged UDA queue implementation RDMA/irdma: Add HMC backing store setup functions RDMA/irdma: Implement HW Admin Queue OPs RDMA/irdma: Implement device initialization definitions RDMA/irdma: Register auxiliary driver and implement private channel OPs i40e: Register auxiliary devices to provide RDMA i40e: Prep i40e header for aux bus conversion ice: Register auxiliary device to provide RDMA ice: Implement iidc operations ice: Initialize RDMA support iidc: Introduce iidc.h i40e: Replace one-element array with flexible-array member
