====================
Intel Wired LAN Driver Updates 2024-10-08 (ice, i40e, igb, e1000e)

This series contains updates to ice, i40e, igb, and e1000e drivers.

For ice:

Marcin allows driver to load, into safe mode, when DDP package is
missing or corrupted and adjusts the netif_is_ice() check to
account for when the device is in safe mode. He also fixes an
out-of-bounds issue when MSI-X are increased for VFs.

Wojciech clears FDB entries on reset to match the hardware state.

For i40e:

Aleksandr adds locking around MACVLAN filters to prevent memory leaks
due to concurrency issues.

For igb:

Mohamed Khalfella adds a check to not attempt to bring up an already
running interface on non-fatal PCIe errors.

For e1000e:

Vitaly changes board type for I219 to more closely match the hardware
and stop PHY issues.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:

ice: Flush FDB entries before reset

Triggering the reset while in switchdev mode causes
errors[1]. Rules are already removed by this time
because switch content is flushed in case of the reset.
This means that rules were deleted from HW but SW
still thinks they exist so when we get
SWITCHDEV_FDB_DEL_TO_DEVICE notification we try to
delete not existing rule.

We can avoid these errors by clearing the rules
early in the reset flow before they are removed from HW.
Switchdev API will get notified that the rule was removed
so we won't get SWITCHDEV_FDB_DEL_TO_DEVICE notification.
Remove unnecessary ice_clear_sw_switch_recipes.

ice: Fix netif_is_ice() in Safe Mode

netif_is_ice() works by checking the pointer to netdev ops. However, it
only checks for the default ice_netdev_ops, not ice_netdev_safe_mode_ops,
so in Safe Mode it always returns false, which is unintuitive. While it
doesn't look like netif_is_ice() is currently being called anywhere in Safe
Mode, this could change and potentially lead to unexpected behaviour.

Merge patch series "remove size limit on XIP kernel"

Nam Cao <namcao@linutronix.de> says:

Hi,

For XIP kernel, the writable data section is always at offset specified in
XIP_OFFSET, which is hard-coded to 32MB.

Unfortunately, this means the read-only section (placed before the
writable section) is restricted in size. This causes build failure if the
kernel gets too large.

This series remove the use of XIP_OFFSET one by one, then remove this
macro entirely at the end, with the goal of lifting this size restriction.

Also some cleanup and documentation along the way.

Introducing Multi-Path DMA Support for mlx5 RDMA Driver

From Yishai,

Overview
--------
This patch series aims to enable multi-path DMA support, allowing an
mlx5 RDMA device to issue DMA commands through multiple paths. This
feature is critical for improving performance and reaching line rate
in certain environments where issuing PCI transactions over one path
may be significantly faster than over another. These differences can
arise from various PCI generations in the system or the specific system
topology.

To achieve this functionality, we introduced a data direct DMA device
that can serve the RDMA device by issuing DMA transactions on its
behalf.

The main key features and changes are described below.

Multi-Path Discovery
--------------------
API Implementation:
* Introduced an API to discover multiple paths for a given mlx5 RDMA
device.
IOCTL Command:
* Added a new IOCTL command, MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH, to
the DEVICE object. When an affiliated Data-Direct/DMA device is present,
its sysfs path is returned.

Feature Activation by mlx5 RDMA Application
-------------------------------------------
UVERBS Extension:
* Extended UVERBS_METHOD_REG_DMABUF_MR over UVERBS_OBJECT_MR to include
mlx5 extended flags.
Access Flag:
* Introduced the MLX5_IB_UAPI_REG_DMABUF_ACCESS_DATA_DIRECT flag, allowing
applications to request the use of the affiliated DMA device for DMABUF
registration.

Data-Direct/DMA Device
----------------------
New Driver:
* Introduced a new driver to manage the new DMA PF device ID (0x2100).
Its registration/un-registration is handled as part of the mlx5_ib init/exit
flows, with mlx5 IB devices as its clients.
Functionality:
* The driver does not interface directly with the firmware (no command interface,
no caps, etc.) but works over PCI to activate its DMA functionality. It serves
as the DMA device for efficiently accessing other PCI devices (e.g., GPU PF) and
reads its VUID over PCI to handle NICs registrations with the same VUID.

mlx5 IB RDMA Device
---------------------------
VUID Query:
* Reads its affiliated DMA PF VUID via the QUERY_VUID command with the data_direct
bit set.
Driver Registration:
* Registers with the DMA PF driver to be notified upon bind/unbind.
Application Request Handling:
* Uses the DMA PF device upon application request as described above.

DMABUF over Umem
----------------
Introduced an option to obtain a DMABUF UMEM using a different DMA
device instead of the IB device, allowing the device to register over
IOMMU with the expected DMA device for a given buffer registration.

Further details are provided in the commit logs of the patches in this series.

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.

The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.

Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.

Follows the list of the rest of the changes grouped by type of
change.

Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.

The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.

The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.

Constified a few global data structures in the virtio driver.

The Renesas driver simplifies the bus speed handling in the init
function making it more readable.

Improved an if/else statement in probe function of the Renesas
R-Car driver.

The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().

Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.

Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.

Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.

Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.

The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.

In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.

New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.

New support
-----------
Added support for:

- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.

The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.

Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.

Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.

The i2c-sprd binding has been converted to YAML.
