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.
