      ====================
      net: add and use rx_nohandler stat counter
      
      The network core tries to keep track of dropped packets, but some packets
      you wouldn't really call dropped, so much as intentionally ignored, under
      certain circumstances. One such case is that of bonding and team device
      slaves that are currently inactive. Their respective rx_handler functions
      return RX_HANDLER_EXACT (the only places in the kernel that return that),
      which ends up tracking into the network core's __netif_receive_skb_core()
      function's drop path, with no pt_prev set. On a noisy network, this can
      result in a very rapidly incrementing rx_dropped counter, not only on the
      inactive slave(s), but also on the master device, such as the following:
      
      $ cat /proc/net/dev
      Inter-|   Receive                                                |  Transmit

      In this scenario, p5p1, p5p2 and p7p1 are all inactive slaves in an
      active-backup bond0, and you can see that all three have high drop counts,
      with the master bond0 showing a tally of all three.
      
      I know that this was previously discussed some here:
      
          http://www.spinics.net/lists/netdev/msg226341.html
      
      It seems additional counters never came to fruition, so this is a first
      attempt at creating one of them, so that we stop calling these drops,
      which for users monitoring rx_dropped, causes great alarm, and renders the
      counter much less useful for them.
      
      This adds a sysfs statistics node and makes the counter available via
      netlink.
      
      Additionally, I'm not certain if this set qualifies for net, or if it
      should be put aside and resubmitted for net-next after 4.5 is put to
      bed, but I do have users who consider this an important bugfix.
      
      This has been tested quite a bit on x86_64, and now lightly on i686 as
      well, to verify functionality of updates to netdev_stats_to_stats64()
      on 32-bit arches.

      net/core: relax BUILD_BUG_ON in netdev_stats_to_stats64 · 9256645a
      Jarod Wilson authored
      The netdev_stats_to_stats64 function copies the deprecated
      net_device_stats format stats into rtnl_link_stats64 for legacy support
      purposes, but with the BUILD_BUG_ON as it was, it wasn't possible to
      extend rtnl_link_stats64 without also extending net_device_stats. Relax
      the BUILD_BUG_ON to only require that rtnl_link_stats64 is larger, and
      zero out all the stat counters that aren't present in net_device_stats.

      tipc: fix link attribute propagation bug · d01332f1
      Richard Alpe authored
      Changing certain link attributes (link tolerance and link priority)
      from the TIPC management tool is supposed to automatically take
      effect at both endpoints of the affected link.
      
      Currently the media address is not instantiated for the link and is
      used uninstantiated when crafting protocol messages designated for the
      peer endpoint. This means that changing a link property currently
      results in the property being changed on the local machine but the
      protocol message designated for the peer gets lost. Resulting in
      property discrepancy between the endpoints.
      
      In this patch we resolve this by using the media address from the
      link entry and using the bearer transmit function to send it. Hence,
      we can now eliminate the redundant function tipc_link_prot_xmit() and
      the redundant field tipc_link::media_addr.
      
      Fixes: 2af5ae37 (tipc: clean up unused code and structures)

      Jeff Kirsher says:
      
      ====================
      40GbE Intel Wired LAN Driver Updates 2016-02-03
      
      This series contains updates to i40e and i40evf only.
      
      Kiran adds the MAC filter element to the end of the list instead of HEAD
      just in case there are ever any ordering issues in the future.
      
      Anjali fixes several RSS issues, first fixes the hash PCTYPE enable for
      X722 since it supports a broader selection of PCTYPES for TCP and UDP.
      Then fixes a bug in XL710, X710, and X722 support for RSS since we cannot
      reduce the 4-tuple for RSS for TCP/IPv4/IPv6 or UDP/IPv4/IPv6 packets
      since this requires a product feature change coming in a later release.
      Cleans up the reset code where the restart-autoneg workaround is
      applied, since X722 does not need the workaround, add a flag to indicate
      which MAC and firmware version require the workaround to be applied.
      Adds new device id's for X722 and code to add their support.  Also
      adds another way to access the RSS keys and lookup table using the admin
      queue for X722 devices.
      
      Catherine updates the driver to replace the MAC check with a feature
      flag check for 100M SGMII, since it is only support on X722 devices
      currently.
      
      Mitch reworks the VF driver to allow channel bonding, which was not
      possible before this patch due to the asynchronous nature of the admin
      queue mechanism.  Also fixes a rare case which causes a panic if the
      VF driver is removed during reset recovery, resolve this by setting the
      ring pointers to NULL after freeing them.
      
      Shannon cleans up the driver where device capabilities were defined in
      two different places, and neither had all the definitions, so he
      consolidates the definitions in the admin queue API.  Also adds the new
      proxy-wake-on-lan capability bit available with the new X722 device.
      Lastly, added the new External Device Power Ability field to the
      get_link_status data structure by using a reserved field at the end
      of the structure.
      
      Jesse mimics the ixgbe driver's use of a private work queue in the i40e
      and i40evf drivers to avoid blocking the system work queue.
      
      Greg cleans up the driver to limit the firmware revision checks to
      properly handle DCB configurations from the firmware to the older
      devices which need these checks (specifically X710 and XL710 devices
      only).

      ipvlan: inherit MTU from master device · 296d4856
      Mahesh Bandewar authored
      When we create IPvlan slave; we use ether_setup() and that
      sets up default MTU to 1500 while the master device may have
      lower / different MTU. Any subsequent changes to the masters'
      MTU are reflected into the slaves' MTU setting. However if those
      don't happen (most likely scenario), the slaves' MTU stays at
      1500 which could be bad.
      
      This change adds code to inherit MTU from the master device
      instead of using the default value during the link initialization
      phase.
