      ice: improve print for VF's when adding/deleting MAC filters · be6f7ef6
      Brett Creeley authored
      When we fail to add/delete MAC filters in the VF, the print doesn't
      distinguish between the two. Fix that by printing whether or not we
      failed to add/delete the MAC filter respectively.

      ice: Increase size of Mailbox receive queue for many VFs · 11836214
      Brett Creeley authored
      Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
      queues that are used to communicate with VFs. This is fine for the send
      queue because the PF driver will lock the queue for every single send,
      but for the Mailbox receive queue every VF is posting to its Mailbox
      send queue and the hardware is then handing the message to the PF on its
      Mailbox receive queue. This becomes a problem with many VFs because it
      seems to overburden the Mailbox receive queue on the PF. Fix this by
      increasing the Mailbox receive queue for the PF to 512 entries.
      
      The number 512 was determined based on the number of VFs supported by
      the device. We can have a total of 256 VFs so in the worst case this
      allows the VFs to put 2 messages in the PFs Mailbox receive queue at the
      same time.

      ice: Reduce wait times during VF bringup/reset · 60d628ea
      Brett Creeley authored
      Currently there are a couple places where the VF is waiting too long when
      checking the status of registers. This is causing the AVF driver to
      spin for longer than necessary in the __IAVF_STARTUP state. Sometimes
      it causes the AVF to go into the __IAVF_COMM_FAILED, which may retrigger
      the __IAVF_STARTUP state. Try to reduce the chance of this happening by
      removing unnecessary wait times in VF bringup/resets.

      ice: Do not always bring up PF VSI in ice_ena_vsi() · e6c45149
      Tony Nguyen authored
      During rebuild ice_ena_vsi() is called to recover the VSI state.
      This function assumes the PF VSI is always to be enabled, however,
      it's possible that during reset/rebuild the interface can be
      brought down.  If this occurs, we can attempt to bring up the PF
      VSI on a downed interface which can lead to various crashes. If
      the interface is not running, do not bring up the associated VSI.

      ice: allow empty Rx descriptors · ac6f733a
      Mitch Williams authored
      In some circumstances, the hardware will hand us a receive descriptor
      which has no data attached, but is otherwise valid. The receive code was
      improperly ignoring these descriptors, which result in an infinite loop.
      
      To fix this, change the receive code to process all descriptors,
      regardless of the size of the associated data. Add checks to the
      memory-handling functions to allow for zero size.

      This patch fixes the set local MIB AQ call failures in the DCB rebuild path

      ice: Set WB_ON_ITR when we don't re-enable interrupts · 2ab28bb0
      Brett Creeley authored
      Currently when busy polling is enabled we aren't setting/enabling
      WB_ON_ITR in the driver. This doesn't break the driver, but it does
      cause issues. If we don't enable WB_ON_ITR mode we will still get
      write-backs from hardware during polling when a cache line has been
      filled, but if a cache line is not filled we will not get the
      write-back because WB_ON_ITR is not set. Fix this by enabling
      WB_ON_ITR in the driver when interrupts are disabled.

      ====================
      pull-request: can-next 2019-08-20
      
      this is a pull request for net-next/master consisting of 18 patches.
      
      The first patch is by Geert Uytterhoeven, it removes the unused platform
      data support from the rcar_can driver.
      
      A patch by Nishka Dasgupta marks the structure peak_pciec_i2c_bit_ops in
      the peak_pci driver as constant.
      
      A patch by me removes the custom DMA support from the hi311x driver.
      
      The next 4 patches target the tcan4x5x driver and are also by me, they
      first clean up the driver a bit, and then add missing error handling and
      fix a bug in the length calculation in the regmap callbacks.
      
      The next 2 patches are by me for the m_can_platform driver, they also
      remove unneeded casts and add missing error handling.
      
      The remaining 9 patches all target the mcp251x driver. The first 5 are
      clean up patches by me, the next relaxes the timing in the
      mcp251x_hw_reset() function. Alexander Shiyan's patch improves the name
      which is used while registering the interrupt handler. Phil Elwell's
      patch improves the mcp251x_open() function to use the DT-supplied
      interrupt flags instead of hard coding them. The final patch is again by
      me, it removes the custom DMA support from the hi311x driver.

      s390/qeth: merge qeth_reply struct into qeth_cmd_buffer · 308946b0
      Julian Wiedmann authored
      Except for card->read_cmd, every cmd we issue now passes through
      qeth_send_control_data() and allocates a qeth_reply struct. The way we
      use this struct requires additional refcounting, and pointer tracking.
      
      Clean up things by moving most of qeth_reply's content into the main
      cmd struct. This keeps things in one place, saves us the additional
      refcounting and simplifies the overall code flow.
      A nice little benefit is that we can now match incoming replies against
      the pending requests themselves, without caching the requests' seqnos.
      
      The qeth_reply struct stays around for a little bit longer in a shrunk
      form, to avoid touching every single callback.

      net/mlx5e: Fix deallocation of non-fully init encap entries · 3c140dd5

      Recent rtnl lock dependency refactoring changed encap entry attach code to

      to allow concurrent tc users to wait on completion for encap entry to
      finish initialization. That change required all the users of encap entry to
      obtain reference to it first and for caller that creates encap to put
      reference to it on error, instead of freeing the entry memory directly.
      However, releasing reference to such encap entry that wasn't fully
      initialized causes NULL pointer dereference in
      mlx5e_rep_encap_entry_detach() which expects e->out_dev to be set and encap
      to be attached to nhe:

      To fix the issue, set e->compl_result to positive value after encap was
      initialized successfully. Check e->compl_result value in
      mlx5e_encap_dealloc() and only detach and dealloc encap if the value is
      positive.
      
      Fixes: d589e785 ("net/mlx5e: Allow concurrent creation of encap entries")
