Subject: [pull request][net-next 00/16] Mellanox, mlx5 devlink RX health
 reporters

Hi Dave,

This series is adding a new devlink health reporter for RX related
errors from Aya.

Last two patches from Vlad and Gavi, are trivial fixes for previously
submitted patches on this release cycle.

For more information please see tag log below.

Please pull and let me know if there is any problem.

Thanks,

  net/mlx5: Fix the order of fc_stats cleanup (2019-08-15 12:02:13 -0700)

----------------------------------------------------------------
mlx5-updates-2019-08-15

This patchset introduces changes in mlx5 devlink health reporters.
The highlight of these changes is adding a new reporter: RX reporter

mlx5 RX reporter: reports and recovers from timeouts and RX completion
error.

1) Perform TX reporter cleanup. In order to maintain the
code flow as similar as possible between RX and TX reporters, start the
set with cleanup.

2) Prepare for code sharing, generalize and move shared
functionality.

3) Refactor and extend TX reporter diagnostics information
to align the TX reporter diagnostics output with the RX reporter's
diagnostics output.

4) Add helper functions Patch 11: Add RX reporter, initially
supports only the diagnostics call back.

5) Change ICOSQ (Internal Operations Send Queue) open/close flow to
avoid race between interface down and completion error recovery.

6) Introduce recovery flows for RX ring population timeout on ICOSQ,
and for completion errors on ICOSQ and on RQ (Regular receive queues).

8) Include RX reporters in mlx5 documentation.

Last two patches of this series, are trivial fixes for previously
submitted patches on this release cycle.
