      ====================
      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).
      
      7) Include RX reporters in mlx5 documentation.
      
      8) Last two patches of this series, are trivial fixes for previously
      submitted patches on this release cycle.

      ====================
      100GbE Intel Wired LAN Driver Updates 2019-08-20
      
      This series contains updates to ice driver only.
      
      Brett fixes the detection of a hung transmit ring by checking the
      software based tail (next_to_use) to determine if there is pending work.
      Updates the driver to assume that using more than one receive queue per
      receive ring container is a rare case, so use unlikely() in the case
      were we actually need to divide our budget for multiple queues.  Fixed
      an issue where the write back on ITR bit was not being set when
      interrupts are disabled, which was causing only write backs when polling
      only when a cache line is filled.  Cleans up unnecessary wait times
      during VF bring up and reset paths.  Increased the mailbox size for
      receive queues that are used to communicate with VFs to accommodate the
      large number of VFs that the driver can support.
      
      Akeem restructures the initialization flows for VFs, including how VFs
      are configured and resources allocated to improve flows so that when we
      clean up resources, we do not try to free resources that were never
      allocated.  Organizes code to ensure that VF specific code is located in
      the SR-IOV specific file.
      
      Paul fixes an issue when setting the pause parameter which was
      incorrectly blocking users from changing receive or transmit pause
      settings.  Ensure register access for MSIX vector index is only done in
      the PF space and not absolute device space.
      
      Usha fixes a potential kernel hang in the DCB rebuild path when in CEE
      mode, where the ETS recommended DCB configuration is not being set or
      set correctly.
      
      Mitch updates the driver to process all receive descriptors, regardless
      of the size of the associated data.
      
      Tony fixes and issue during the reset/rebuild path of a PF VSI where we
      were assuming that the PF VSI was always to be enabled, which can
      attempt to bring up a PF VSI on a downed interface which can lead to
      various crashes.
      
      Pawel fixes up variable definitions to match the type of data being
      stored.
      
      v2: Dropped patch 1 of the series to add ethtool support to query/add
          channels on a VSI, while we re-qork the functionality to match the
          ethtool expected behavior to report combined (Tx and Rx) numbers.
      v3: Updated patch 4 to use kzalloc() and kfree() instead devm_kzalloc()
          and devm_kfree().
