Hi Dave,

This series contains Misc updates and cleanups for mlx5e rx path
and SQ recovery feature for tx path.

For more information please see tag log below.

Please pull and let me know if there's any problem.

Thanks,

  net/mlx5e: Recover Send Queue (SQ) from error state (2018-03-27 17:29:28 -0700)

----------------------------------------------------------------
mlx5-updates-2018-03-27 (Misc updates & SQ recovery)

This series contains Misc updates and cleanups for mlx5e rx path
and SQ recovery feature for tx path.

>From Tariq: (RX updates)
    - Disable Striding RQ when PCI devices, striding RQ limits the use
      of CQE compression feature, which is very critical for slow PCI
      devices performance, in this change we will prefer CQE compression
      over Striding RQ only on specific "slow"  PCIe links.
    - RX path cleanups
    - Private flag to enable/disable striding RQ

>From Eran: (TX fast recovery)
    - TX timeout logic improvements, fast SQ recovery and TX error reporting
      if a HW error occurs while transmitting on a specific SQ, the driver will
      ignore such error and will wait for TX timeout to occur and reset all
      the rings. Instead, the current series improves the resiliency for such
      HW errors by detecting TX completions with errors, which will report them
      and perform a fast recover for the specific faulty SQ even before a TX
      timeout is detected.

Thanks,
Saeed.
