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'

quoted

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.

This rdma series is built against the shared branch iwl-next [1] which
is expected to be merged into rdma-next first for the netdev parts.

Okay, applied to for-next, please keep on top of any 0-day stuff that comes out. I
need it all fixed in 2 weeks

Sure.

Tatyana is out till June 7th, so I sent a new PR for the user-space bit with the updated kernel headers commit.
