Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
"A new Pensando ionic driver, a new Gen 3 HW support for Intel irdma,
and lots of small bnxt_re improvements.

- Small bug fixes and improves to hfi1, efa, mlx5, erdma, rdmarvt,
siw

- Allow userspace access to IB service records through the rdmacm

- Optimize dma mapping for erdma

- Fix shutdown of the GSI QP in mana

- Support relaxed ordering MR and fix a corruption bug with mlx5 DMA
Data Direct

- Many improvement to bnxt_re:
- Debugging features and counters
- Improve performance of some commands
- Change flow_label reporting in completions
- Mirror vnic
- RDMA flow support

- New RDMA driver for Pensando Ethernet devices: ionic

- Gen 3 hardware support for the Intel irdma driver

- Fix rdma routing resolution with VRFs"

RDMA/irdma: Add GEN3 virtual QP1 support

Add a new RDMA virtual channel op during QP1 creation that allow the
Control Plane (CP) to virtualize a regular QP as QP1 on non-default
RDMA capable vPorts.

RDMA/irdma: Add GEN3 virtual QP1 support

Add a new RDMA virtual channel op during QP1 creation that allow the
Control Plane (CP) to virtualize a regular QP as QP1 on non-default
RDMA capable vPorts. Additionally, the CP will return the Qsets to use
on the ib_device of the vPort.

RDMA/irdma: Add GEN3 support for AEQ and CEQ

Extend support for GEN3 devices by programming the necessary hardware
IRQ registers and the updated descriptor fields for the Asynchronous
Event Queue (AEQ) and Completion Event Queue (CEQ). Introduce a RDMA
virtual channel operation with the Control Plane (CP) to associate
interrupt vectors appropriately with AEQ and CEQ. Add new Asynchronous
Event (AE) definitions specific to GEN3.

Additionally, refactor the AEQ and CEQ setup into the irdma_ctrl_init_hw
device control initialization routine.

This completes the PCI device level initialization for RDMA in the core
driver.

RDMA/irdma: Add GEN3 core driver support

Introduce support for the GEN3 auxiliary core driver, which is
responsible for initializing PCI-level RDMA resources.

Facilitate host-driver communication with the device's Control Plane (CP)
to discover capabilities and perform privileged operations through an
RDMA-specific messaging interface built atop the IDPF mailbox and virtual
channel protocol.

Establish the RDMA virtual channel message interface and incorporate
operations to retrieve the hardware version and discover capabilities
from the CP.

Additionally, set up the RDMA MMIO regions and initialize the RF structure.
