[pull request][net V2 00/10] mlx5 fixes 2023-04-19

[Saeed Mahameed]

From: Saeed Mahameed <saeedm@nvidia.com>

V1->v2:
  - #3, Remove "inline" keyword from a function declaration in c file.
  - #1, FYI Automation is reporting "author Signed-off-by missing" but
    it is not ! I manually checked, so nothing was changed in patch 1

This series provides bug fixes to mlx5 driver.
Please pull and let me know if there is any problem.

Thanks,
Saeed.

[net V2 01/10] net/mlx5e: Don't clone flow post action attributes second time

[Saeed Mahameed]

From: Vlad Buslov <vladbu@nvidia.com>

The code already clones post action attributes in
mlx5e_clone_flow_attr_for_post_act(). Creating another copy in
mlx5e_tc_post_act_add() is a erroneous leftover from original
implementation. Instead, assign handle->attribute to post_attr provided by
the caller. Note that cloning the attribute second time is not just
wasteful but also causes issues like second copy not being properly updated
in neigh update code which leads to following use-after-free:

Currently when creating per vport table, create flags are hardcoded.
Devlink encap mode is set based on user input and HW capability.

[net V2 04/10] net/mlx5: E-switch, Don't destroy indirect table in split rule

[Saeed Mahameed]

From: Chris Mi <cmi@nvidia.com>

Source port rewrite (forward to ovs internal port or statck device) isn't
supported in the rule of split action. So there is no indirect table in
split rule. The cited commit destroyes indirect table in split rule. The
indirect table for other rules will be destroyed wrongly. It will cause
traffic loss.

Fix it by removing the destroy function in split rule. And also remove
the destroy function in error flow.

[net V2 06/10] net/mlx5e: Fix error flow in representor failing to add vport rx rule

[Saeed Mahameed]

From: Roi Dayan <roid@nvidia.com>

On representor init rx error flow the flow steering pointer is being
released so mlx5e_attach_netdev() doesn't have a valid fs pointer
in its error flow. Make sure the pointer is nullified when released
and add a check in mlx5e_fs_cleanup() to verify fs is not null
as representor cleanup callback would be called anyway.

[net V2 08/10] net/mlx5: Use recovery timeout on sync reset flow

[Saeed Mahameed]

From: Moshe Shemesh <moshe@nvidia.com>

Use the same timeout for sync reset flow and health recovery flow, since
the former involves driver's recovery from firmware reset, which is
similar to health recovery. Otherwise, in some cases, such as a firmware
upgrade on the DPU, the firmware pre-init bit may not be ready within
current timeout and the driver will abort loading back after reset.

[net V2 09/10] net/mlx5e: Nullify table pointer when failing to create

[Saeed Mahameed]

From: Aya Levin <ayal@nvidia.com>

On failing to create promisc flow steering table, the pointer is
returned with an error. Nullify it so unloading the driver won't try to
destroy a non existing table.

Failing to create promisc table may happen over BF devices when the ARM
side is going through a firmware tear down. The host side start a
reload flow. While the driver unloads, it tries to remove the promisc
table. Remove WARN in this state as it is a valid error flow.
