[net 1/9] net/mlx5e: Remove WARN_ON when trying to offload an unsupported TLS cipher/version

[Saeed Mahameed]

From: Gal Pressman <gal@nvidia.com>

The driver reports whether TX/RX TLS device offloads are supported, but
not which ciphers/versions, these should be handled by returning
-EOPNOTSUPP when .tls_dev_add() is called.

Remove the WARN_ON kernel trace when the driver gets a request to
offload a cipher/version that is not supported as it is expected.

[net 2/9] net/mlx5e: TC, Fix post_act to not match on in_port metadata

[Saeed Mahameed]

From: Maor Dickman <maord@nvidia.com>

The cited commit changed CT to use multi table actions post act infrastructure instead
of using it own post act infrastructure, this broke decap during VF tunnel offload
(Stack devices) with CT due to wrong match on in_port metadata in the post act table.
This changed only broke VF tunnel offload because it modify the packet in_port metadata
to be VF metadata and it isn't propagate the post act creation.

Fixed by modify post act rules to match only on fte_id and not match on in_port metadata
which isn't needed.

[net 3/9] net/mlx5e: Fix the value of MLX5E_MAX_RQ_NUM_MTTS

[Saeed Mahameed]

From: Maxim Mikityanskiy <maximmi@nvidia.com>

MLX5E_MAX_RQ_NUM_MTTS should be the maximum value, so that
MLX5_MTT_OCTW(MLX5E_MAX_RQ_NUM_MTTS) fits into u16. The current value of
1 << 17 results in MLX5_MTT_OCTW(1 << 17) = 1 << 16, which doesn't fit
into u16. This commit replaces it with the maximum value that still
fits u16.

[net 4/9] net/mlx5e: xsk: Account for XSK RQ UMRs when calculating ICOSQ size

[Saeed Mahameed]

From: Maxim Mikityanskiy <maximmi@nvidia.com>

ICOSQ is used to post UMR WQEs for both regular RQ and XSK RQ. However,
space in ICOSQ is reserved only for the regular RQ, which may cause
ICOSQ overflows when using XSK (the most risk is on activating
channels).

This commit fixes the issue by reserving space for XSK UMR WQEs as well.
As XSK may be enabled without restarting the channel and recreating the
ICOSQ, this space is reserved unconditionally.

[net 5/9] net/mlx5e: Fix calculations related to max MPWQE size

[Saeed Mahameed]

From: Maxim Mikityanskiy <maximmi@nvidia.com>

Before commit 76c31e5f7585 ("net/mlx5e: Use FW limitation for max MPW
WQEBBs"), the maximum size of MPWQE in WQEBBs was hardcoded as a driver
constant. That commit started using the firmware capability that can
further limit the size, however, it unintentionally changed a few
things:

1. The calculation of MLX5E_MAX_KLM_PER_WQE used the size in DS, which
was replaced by the size in WQEBBs, making the resulting value 4 times
smaller.

2. MLX5E_TX_MPW_MAX_WQEBBS used to be aligned to the cache line size
(either 64 or 128 bytes, i.e. 1 or 2 WQEBBs), but it's no longer the
case if the firmware capability is smaller than the driver maximum.

Fix both issues by using the correct units for MLX5E_MAX_KLM_PER_WQE and
by aligning mlx5e_get_sw_max_sq_mpw_wqebbs after taking the minimum.

Besides fixing the arithmetics in calculation of MLX5E_MAX_KLM_PER_WQE,
also use appropriate constants: `size of BSF * num of DS per WQEBB *
number of WQEBBs` (the calculation before the blamed commit) doesn't
make much sense to calculate the WQE size in bytes, so just use `size of
WQEBB * number of WQEBBs`.

While at it, replace the types that hold the number of WQEBBs by u8.
These values don't exceed 16, and it allows to fill holes in two
structs.

[net 6/9] net/mlx5e: Modify slow path rules to go to slow fdb

[Saeed Mahameed]

From: Vlad Buslov <vladbu@nvidia.com>

While extending available range of supported chains/prios referenced commit
also modified slow path rules to go to FT chain instead of actual slow FDB.
However neither of existing users of the MLX5_ATTR_FLAG_SLOW_PATH
flag (tunnel encap entries with invalid encap and flows with trap action)
need to match on FT chain. After bridge offload was implemented packets of
such flows can also be matched by bridge priority tables which is
undesirable. Restore slow path flows implementation to redirect packets to
slow_fdb.

[net 7/9] net/mlx5: Adjust log_max_qp to be 18 at most

[Saeed Mahameed]

From: Maher Sanalla <msanalla@nvidia.com>

The cited commit limited log_max_qp to be 17 due to FW capabilities.
Recently, it turned out that there are old FW versions that supported
more than 17, so the cited commit caused a degradation.

Thus, set the maximum log_max_qp back to 18 as it was before the
cited commit.

[net 8/9] net/mlx5: DR, Fix SMFS steering info dump format

[Saeed Mahameed]

From: Yevgeny Kliteynik <kliteyn@nvidia.com>

Fix several issues in SMFS steering info dump:
 - Fix outdated macro value for matcher mask in the SMFS debug dump format.
   The existing value denotes the old format of the matcher mask, as it was
   used during the early stages of development, and it results in wrong
   parsing by the steering dump parser - wrong fields are shown in the
   parsed output.
 - Add the missing destination table to the dumped action.
   The missing dest table handle breaks the ability to associate between
   the "go to table" action and the actual table in the steering info.

[net 9/9] net/mlx5: Fix driver use of uninitialized timeout

[Saeed Mahameed]

From: Shay Drory <shayd@nvidia.com>

Currently, driver is setting default values to all timeouts during
function setup. The offending commit is using a timeout before
function setup, meaning: the timeout is 0 (or garbage), since no
value have been set.
This may result in failure to probe the driver:
mlx5_function_setup:1034:(pid 69850): Firmware over 4294967296 MS in pre-initializing state, aborting
probe_one:1591:(pid 69850): mlx5_init_one failed with error code -16

Hence, set default values to timeouts during tout_init()
