      ====================
      net: qmi_wwan: MDM9x30 support
      
      We add new device IDs all the time, often without any testing on
      actual hardware. This is usually OK as long as the device is similar
      to already supported devices, using the same chipset and firmware
      basis.  But the Sierra Wireless MC7455 is an example of a new chipset
      generation. Adding it based on assumed similarity with its ancestors
      proved too optimistic.
      
      This series adds the missing bits and pieces necessary to support LTE
      Advanced modems based on the Qualcomm MDM9x30 chipset. A big thanks to
      Sierra Wireless for providing MC7455 samples for testing
      
      The most important change is the "raw-ip" support. The series also
      adds a necessary control request, removes an unsupported device ID,
      and adds a driver specific entry in MAINTAINERS.
      
      A few random notes about "raw-ip":
      
      "I rather have these all running in raw IP mode. The 802.3 framing is
      utterly stupid." - Marcel Holtmann in Jan 2012 [1]
      
      Marcel was right.  I should have listened to him. What more can I say?
      
      The 802.3 framing has provided a steady supply of firmware bugs for
      many years. We've added driver workarounds for many of these, but
      there are still known bugs where the workaround is so yucky that we
      have refused to apply it. But all that is over now.  The latest
      generation Qualcomm chips no longer supports 802.3 framing at all.
      
      I had two open questions regarding the "raw-ip" userspace API:
      
      1) Should we continue faking an ethernet device, even if we don't use
         the L2 headers on the USB link anymore?
      
         There was a vote in favour of the "headerless" device. This is the
         honest representation of the hardware/firmware interface.
      
      2) What input should the driver base its framing on?
      
         Snooping or directly manipulating QMI is considered out of the
         question. We delegated all QMI handling to userspace from the
         beginning.
      
         We have so far required userspace to configure the firmware for
         "802.3" framing, or fail if that proved impossible.  This
         requirement is now changed.  Userspace must now inform the driver
         if it negotiates "raw-ip" framing.  Two alternative interfaces were
         proposed:
          - ethtool private driver flag, or
          - sysfs file
      
         The NetworkManager/ModemManager developers were in favour of the
         sysfs alternative.
      
      These questions (or any other you migh have :) are of course still
      open.  This patch set presents the solutions I currently prefer,
      considering the above.
      
      All comments are appreciated, even simple '+1' ones.

      net: qmi_wwan: support "raw IP" mode · 32f7adf6
      Bjørn Mork 提交于
      QMI wwan devices have traditionally emulated ethernet devices
      by default. But they have always had the capability of operating
      without any L2 header at all, transmitting and receiving "raw"
      IP packets over the USB link.  This firmware feature used to be
      configurable through the QMI management protocol.
      
      Traditionally there was no way to verify the firmware mode
      without attempting to change it.  And the firmware would often
      disallow changes anyway, i.e. due to a session already being
      established.  In some cases, this could be a hidden firmware
      internal session, completely outside host control.  For these
      reasons, sticking with the "well known" default mode was safest.
      
      But newer generations of QMI hardware and firmware have moved
      towards defaulting to "raw IP" mode instead, followed by an
      increasing number of bugs in the already buggy "802.3" firmware
      implementation. At the same time, the QMI management protocol
      gained the ability to detect the current mode.  This has enabled
      the userspace QMI management application to verify the current
      firmware mode without trying to modify it.
      
      Following this development, the latest QMI hardware and firmware
      (the MDM9x30 generation) has dropped support for "802.3" mode
      entirely. Support for "raw IP" framing in the driver is therefore
      necessary for these devices, and to a certain degree to work
      around problems with the previous generation,
      
      This patch adds support for "raw IP" framing for QMI devices,
      changing the netdev from an ethernet device to an ARPHRD_NONE
      p-t-p device when "raw IP" framing is enabled.
      
      The firmware setup is fully delegated to the QMI userspace
      management application, through simple tunneling of the QMI
      protocol. The driver will therefore not know which mode has been
      "negotiated" between firmware and userspace. Allowing userspace
      to inform the driver of the result through a sysfs switch is
      considered a better alternative than to change the well established
      clean delegation of firmware management to userspace.

      net: qmi_wwan: MDM9x30 specific power management · 93725149
      Bjørn Mork 提交于
      MDM9x30 based modems appear to go into a deeper sleep when
      suspended without "Remote Wakeup" enabled.  The QMI interface
      will not respond unless a "set DTR" control request is sent
      on resume. The effect is similar to a QMI_CTL SYNC request,
      resetting (some of) the firmware state.
      
      We allow userspace sessions to span multiple character device
      open/close sequences.  This means that userspace can depend
      on firmware state while both the netdev and the character
      device are closed.  We have disabled "needs_remote_wakeup" at
      this point to allow devices without remote wakeup support to
      be auto-suspended.
      
      To make sure the MDM9x30 keeps firmware state, we need to
      keep "needs_remote_wakeup" always set. We also need to
      issue a "set DTR" request to enable the QMI interface.

      ====================
      net:hns: Add support of Hip06 SoC to the Hislicon Network Subsystem
      
      This PATCH V7 addresses the TAB formatting comments by
      Sergei Shtylyov. Missing TABs at some other palces have
      also been corrected.
      
      PATCH V6:
      This addresses the review comments provided by
      David Miller over the existing use of ENABLE/DISABLE
      hash defines with the code. These hash defines are doing
      a similar job as implicit type bool would do. So these are
      kind of duplicate and are redundant.
      
      PATCH V5:
      This PATCH addresses the review comments by Yuval Mintz
       <Yuval.Mintz@qlogic.com>. This rework of comments are basically
       related to:
       1) styling of the code,
       2) RSS default Key initiailization related code
       3) redundant code removal
      
      PATCH V4:
      This addresses the review comment provided by
      Sergei Shtylyov. The changelog of every patch has also
      been modified.
      
      PATCH V3:
       Addresses the review comment floated by David Miller
      
      PATCH V2:
      1) Bug Fixes and Clean-up: Internally identified
      2) Addresses internal review comments by Kenneth Lee and
         by Huang Daode
      3) Addresses the review comment from "Yisen.Zhuang(Zhuangyuzeng)"
      4) Adds fix from Fengguang Wu for an error generated from
         "kbuild test robot" from Intel
      5) Ethtool support for TSO set option from Lisheng
      
      PATCH V1:
      Adds initial support of Hip06 SoC with below changes:
      This patch-set adds support of new Hisilicon Hip06 SoC to the existing
      (already part of net-next) HNS ethernet driver for Hip05 SoC. Hip06 is
      a multi-core SoC and is a derivative of Hip05 SoC with lots of new
      hardware featres supported like RSS, TSO, hardware VLAN assist etc.
      
      The changes in the driver are mainly due to following:
       1) changes in the DMA descriptor provided by the Hip06 ethernet
          hardware. These changes need to co-exist with already present
          Hip05 DMA descriptor and its operating functions. The decision
          to choose the correct type of DMA descriptor is taken dynamically
          depending upon the version of the hardware (i.e. V1/hip05 or
          V2/hip06, see already existing hisilicon-hns-nic.txt binding file
          for the detailed description version and naming).
       2) To support new features added to the Hip06 ethernet hardware:
          a. RSS (Receive Side Scaling)
          b. TSO (TCP Segment Offload)
          c. Hardware VLAN support (currently we are initializing hardware
             to not assist in stripping the vlan tag at hardware level.
             Proper support of this feature and ethtool would come after
             these patches have been accepted)
      
      Kindly note that, this patchset has been based on latest net-next.

              - A build improvement from Keith.
              - Update the qemu pci id detection from Matias.
              - Error handling fixes for leaks and other little fixes from
                Sudip and Wenwei.
      
         - fix from Eric where BLKRRPART would not return EBUSY for whole
           device mounts, only when partitions were mounted.
      
         - fix from Jan Kara, where EOF O_DIRECT reads would return
           negatively.
      
         - remove check for rq_mergeable() when checking limits for cloned
           requests.  The check doesn't make any sense.  It's assuming that
           since NOMERGE is set on the request that we don't have to
           recalculate limits since the request didn't change, but that's not
           true if the request has been redirected.  From Hannes.
      
         - correctly get the bio front segment value set for single segment
           bio's, fixing a BUG() in blk-merge.  From Ming"

      Pull tracing fix from Steven Rostedt:
       "During the merge window I added a new file that is used to filter
        trace events on pids.  It filters all events where only tasks with
        their pid in that file exists.  It also handles the sched_switch and
        sched_wakeup trace events where the current task does not have its pid
        in the file, but the task either being switched to or awaken does.
      
        Unfortunately, I forgot about sched_wakeup_new and sched_waking.  Both
        of these tracepoints use the same class as the sched_wakeup
        tracepoint, and they too should be included in what gets filtered by
        the set_event_pid file"

      A small set of fixes for 4.4:
       * fix scanning in mac80211 to not actively scan radar
         channels (from Antonio)
       * fix uninitialized variable in remain-on-channel that
         could lead to treating frame TX as remain-on-channel
         and not sending the frame at all
       * remove NL80211_FEATURE_FULL_AP_CLIENT_STATE again, it
         was broken and needs more work, we'll enable it later
       * fix call_rcu() induced use-after-reset/free in mesh
         (that was suddenly causing issues in certain tests)
       * always request block-ack window size 64 as we found
         some APs will otherwise crash (really ...)
       * fix P2P-Device teardown sequence to avoid restarting
         with uninitialized data

      Jérôme Pouiller 提交于
      It is possible to address another chip on same MDIO bus. The case is
      correctly handled for media advertising. It is taken into account
      only if mii_data->phy_id == phydev->addr. However, this condition
      was missing for reset case.

      stmmac: ipq806x: Return error values instead of pointers · ead87637
      Stephen Boyd 提交于
      Typically we return error pointers when we want to use those
      pointers in the non-error case, but this function is just
      returning error pointers or NULL for success. Change the style to
      plain int to follow normal kernel coding styles.

      tipc: fix node reference count bug · dc8d1eb3
      Jon Paul Maloy 提交于
      Commit 5405ff6e ("tipc: convert node lock to rwlock")
      introduced a bug to the node reference counter handling. When a
      message is successfully sent in the function tipc_node_xmit(),
      we return directly after releasing the node lock, instead of
      continuing and decrementing the node reference counter as we
      should do.
      
      This commit fixes this bug.

      ====================
      mvneta: implement ethtool autonegotiation control
      
      These 2 patches add an ability to control the
      autonegotiation via ethtool. For example:
      
      ethtool -s eth0 autoneg off
      ethtool -s eth0 autoneg on
      
      This is needed if you want to connect the mvneta's MII
      to different switches or PHYs: the ones the do support
      the in-band status, and the ones that do not.

      mvneta: implement ethtool autonegotiation control · 0c0744fc
      Stas Sergeev 提交于
      This patch allows to do
      ethtool -s eth0 autoneg off
      ethtool -s eth0 autoneg on
      to disable or enable autonegotiation at run-time.
      Without that functionality, the only way to control the autonegotiation
      is to modify the device tree.
      
      This is needed if you plan to use the same kernel with
      different ethernet switches, the ones that support the in-band
      status and the ones that not.
