[net-next 01/15] net/mlx5: remove redundant clear_bit

[Saeed Mahameed]

From: Moshe Shemesh <moshe@nvidia.com>

When shutdown or remove callbacks are called the driver sets the flag
MLX5_BREAK_FW_WAIT, to stop waiting for FW as teardown was called. There
is no need to clear the bit as once shutdown or remove were called as
there is no way back, the driver is going down. Furthermore, if not
cleared the flag can be used also in other loops where we may wait while
teardown was already called.

Use test_bit() instead of test_and_clear_bit() as there is no need to
clear the flag.

[net-next 02/15] net/mlx5: Stop waiting for PCI up if teardown was triggered

[Saeed Mahameed]

From: Moshe Shemesh <moshe@mellanox.com>

If driver teardown is called while PCI is turned off, there is a race
between health recovery and teardown. If health recovery already started
it will wait 60 sec trying to see if PCI gets back and it can recover,
but actually there is no need to wait anymore once teardown was called.

Use the MLX5_BREAK_FW_WAIT flag which is set on driver teardown to break
waiting for PCI up.

[net-next 05/15] net/mlx5e: Correct SKB room check to use all room in the fifo

[Saeed Mahameed]

From: Rahul Rameshbabu <rrameshbabu@nvidia.com>

Previous check was comparing against the fifo mask. The mask is size of the
fifo (power of two) minus one, so a less than or equal comparator should be
used for checking if the fifo has room for the SKB.

The rest looks fine, do you want me to apply from the list and fix up?

Sorry it wasn't clear to me that it was about the Fixes tag, 
I thought the issue was with targeting the net branch.

Yes that works, Thank you.

Mostly about it getting into stable, the process is a bit 
unpredictable.

[net-next 06/15] net/mlx5e: Rename RQ/SQ adaptive moderation state flag

[Saeed Mahameed]

From: Adham Faris <afaris@nvidia.com>

Dynamic interrupt moderation RQ and SQ feature represented by
MLX5E_RQ_STATE_AM and MLX5E_SQ_STATE_AM enums respectively, is not
consistent with the feature naming in the driver, and with the formal
feature and library names.

Hence, change MLX5E_RQ_STATE_AM and MLX5E_SQ_STATE_AM enum type names in
core/en.h to MLX5E_RQ_STATE_DIM and MLX5E_SQ_STATE_DIM respectively.

[net-next 07/15] net/mlx5e: Stringify RQ SW state in RQ devlink health diagnostics

[Saeed Mahameed]

From: Adham Faris <afaris@nvidia.com>

One of the parameters that is retrieved/printed as a response to
devlink health diagnostics for rx reporter is the RQ SW state.

It's printed as a bitmap decimal number. Printing it as bitmap is
problematic and non informative.

In addition User can't count on SW state without accessing the kernel
sources (mlx5e rq state enum in en.h).

This patch prints RQ SW state in a textual representation, as a key:
value pairs, where disabled rq states will appear as '0' and enabled
ones will appear as '1'.

See below the generated output for rx health diagnostics devlink
command:

$ devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx

[net-next 09/15] net/mlx5e: Add XSK RQ state flag for RQ devlink health diagnostics

[Saeed Mahameed]

From: Adham Faris <afaris@nvidia.com>

Currently RQ health diagnostics doesn't inform the user whether an RQ
is an XSK RQ or not.

Address this, by adding XSK state flag to RQ SW state enum in core/en.h.
XSK will be '1' if current RQ is an XSK RQ, and it will be '0' if it's
not.

In this example below, it can be seen that XSK field value is '1' since
xdpsock program have been attached to channel 0 before issuing the
devlink query command:

$ devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx

Output:

[net-next 11/15] net/mlx5e: Add devlink hairpin queues parameters

[Saeed Mahameed]

From: Gal Pressman <gal@nvidia.com>

We refer to a TC NIC rule that involves forwarding as "hairpin".
Hairpin queues are mlx5 hardware specific implementation for hardware
forwarding of such packets.

Per the discussion in [1], move the hairpin queues control (number and
size) from debugfs to devlink.

Expose two devlink params:
- hairpin_num_queues: control the number of hairpin queues
- hairpin_queue_size: control the size (in packets) of the hairpin queues
