Hi,
This patchset includes small features and misc code enhancements for the
mlx5e driver.
Patches 1-4 by Gal improves the mlx5e ethtool stats implementation, for
example by using standard helpers ethtool_sprintf/puts.
Patch 5 by Carolina adds exposure of RX packet drop counters of VFs/SFs
on their representor.
Patch 6 by me adds a reset option for the FW command interface debugfs
stats entries. This allows explicit FW command interface stats reset
between different runs of a test case.
Patches 7 and 8 are simple cleanups.
Series generated against:
commit 537c2e91d354 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net")
Thanks,
Tariq.

net/mlx5e: Expose the VF/SF RX drop counter on the representor
net/mlx5e: XDP, Fix an inconsistent comment

Use ethtool_sprintf/puts() helper functions which handle the common

pattern of printing a string into the ethtool strings interface and
incrementing the string pointer by ETH_GSTRING_LEN.
The int return value in mlx5e_self_test_fill_strings() is not removed as
it is still used to return the number of selftests.

Use ethtool_sprintf/puts() helper functions which handle the common
pattern of printing a string into the ethtool strings interface and
incrementing the string pointer by ETH_GSTRING_LEN.
Change the fill_strings callback to accept a **data pointer, and remove
the index and return value.

Cc: netdev, Saeed Mahameed, Gal Pressman, Leon Romanovsky, Tariq Toukan
From: Gal Pressman <gal@nvidia.com>
The fill_strings() callbacks were changed to accept a **data pointer,
and not rely on propagating the index value.
Make a similar change to fill_stats() callbacks to keep the API
consistent.

Q counters are device-level counters that track specific
events, among which are out_of_buffer events. These events
occur when packets are dropped due to a lack of receive
buffer in the RX queue.
Expose the total number of out_of_buffer events on the
VF/SF to their respective representor, using the
"ethtool -S" under the name of "rx_vport_out_of_buffer".
The "rx_vport_out_of_buffer" equals the sum of all
Q counters out_of_buffer values allocated on the VF/SF.

Resetting stats just before some test/debug case allows us to eliminate
out the impact of previous commands. Useful in particular for the
average latency calculation.
The average_write() callback was unreachable, as "average" is a
read-only file. Extend, rename, and use it for a newly exposed
write-only "reset" file.

Hi Carolina and Tariq,
This looks good to me, but if there is a need to repost for some
other reason perhaps it would be worth mentioning that the commit
where the sinfo parameter was removed from mlx5e_xmit_xdp_frame()
was:
eb9b9fdcafe2 ("net/mlx5e: Introduce extended version for mlx5e_xmit_data")
That notwithstanding,

Hi Carolina and Tariq,
I am wondering if any consideration was given to making this
a generic counter. Buffer exhaustion sounds like something that
other NICs may report too.

I think it's basically rx_missed_errors from rtnl_link_stats64.
mlx5 doesn't currently report it at all, AFAICT.

This is purely mlx5 changes, since you're not listed as the maintainer
it'd be good to add an note to the cover letter explaining your
expectations. Otherwise you may have just typo'ed the subject and
have actually meant it for mlx5-next.

This is targeted for net-next. I should add myself in the proper mlx5

We expose it in ethtool stats.
Note that the "local" RX buffer exhaustion counter exists for a long time.
Here we introduce in the representor kind of a "remote" version of the
counter, to help providers monitor RX drops that occur in the customers'
side.
It follows the local counter hence currently it is not generic.

I thought you'd say that, but we can't apply the rules selectively.
Everyone has "local" counters already when we add the generic ones.
Especially when we start broadening the "have" to encompass other
generations of HW / netdev instance types.

In the normal case, we actual misreport out_of_buffer as rx_dropped....
Carolina is working on a fix for that.
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/tree/drivers/net/ethernet/mellanox/mlx5/core/en_main.c?id=ea2a1cfc3b2019bdea6324acd3c03606b60d71ad#n3793
With regards to the case for VF/SF representors, we will be adding
support for reporting the out_of_buffer statistics through the
rx_missed_errors counter as well.
