      In netdevice.h we removed the structure in net-next that is being
      changes in 'net'.  In macsec.c and rtnetlink.c we have overlaps
      between fixes in 'net' and the u64 attribute changes in 'net-next'.
      
      The mlx5 conflicts have to do with vxlan support dependencies.

      ====================
      Netfilter updates for net-next
      
      The following large patchset contains Netfilter updates for your
      net-next tree. My initial intention was to send you this in two goes but
      when I looked back twice I already had this burden on top of me.
      
      Several updates for IPVS from Marco Angaroni:
      
      1) Allow SIP connections originating from real-servers to be load
         balanced by the SIP persistence engine as is already implemented
         in the other direction.
      
      2) Release connections immediately for One-packet-scheduling (OPS)
         in IPVS, instead of making it via timer and rcu callback.
      
      3) Skip deleting conntracks for each one packet in OPS, and don't call
         nf_conntrack_alter_reply() since no reply is expected.
      
      4) Enable drop on exhaustion for OPS + SIP persistence.
      
      Miscelaneous conntrack updates from Florian Westphal, including fix for
      hash resize:
      
      5) Move conntrack generation counter out of conntrack pernet structure
         since this is only used by the init_ns to allow hash resizing.
      
      6) Use get_random_once() from packet path to collect hash random seed
          instead of our compound.
      
      7) Don't disable BH from ____nf_conntrack_find() for statistics,
         use NF_CT_STAT_INC_ATOMIC() instead.
      
      8) Fix lookup race during conntrack hash resizing.
      
      9) Introduce clash resolution on conntrack insertion for connectionless
         protocol.
      
      Then, Florian's netns rework to get rid of per-netns conntrack table,
      thus we use one single table for them all. There was consensus on this
      change during the NFWS 2015 and, on top of that, it has recently been
      pointed as a source of multiple problems from unpriviledged netns:
      
      11) Use a single conntrack hashtable for all namespaces. Include netns
          in object comparisons and make it part of the hash calculation.
          Adapt early_drop() to consider netns.
      
      12) Use single expectation and NAT hashtable for all namespaces.
      
      13) Use a single slab cache for all namespaces for conntrack objects.
      
      14) Skip full table scanning from nf_ct_iterate_cleanup() if the pernet
          conntrack counter tells us the table is empty (ie. equals zero).
      
      Fixes for nf_tables interval set element handling, support to set
      conntrack connlabels and allow set names up to 32 bytes.
      
      15) Parse element flags from element deletion path and pass it up to the
          backend set implementation.
      
      16) Allow adjacent intervals in the rbtree set type for dynamic interval
          updates.
      
      17) Add support to set connlabel from nf_tables, from Florian Westphal.
      
      18) Allow set names up to 32 bytes in nf_tables.
      
      Several x_tables fixes and updates:
      
      19) Fix incorrect use of IS_ERR_VALUE() in x_tables, original patch
          from Andrzej Hajda.
      
      And finally, miscelaneous netfilter updates such as:
      
      20) Disable automatic helper assignment by default. Note this proc knob
          was introduced by a9006892 ("netfilter: nf_ct_helper: allow to
          disable automatic helper assignment") 4 years ago to start moving
          towards explicit conntrack helper configuration via iptables CT
          target.
      
      21) Get rid of obsolete and inconsistent debugging instrumentation
          in x_tables.
      
      22) Remove unnecessary check for null after ip6_route_output().

      compiler-gcc: require gcc 4.8 for powerpc __builtin_bswap16() · 8634de6d
      Josh Poimboeuf authored
      gcc support for __builtin_bswap16() was supposedly added for powerpc in
      gcc 4.6, and was then later added for other architectures in gcc 4.8.
      
      However, Stephen Rothwell reported that attempting to use it on powerpc
      in gcc 4.6 fails with:
      
        lib/vsprintf.c:160:2: error: initializer element is not constant
        lib/vsprintf.c:160:2: error: (near initialization for 'decpair[0]')
        lib/vsprintf.c:160:2: error: initializer element is not constant
        lib/vsprintf.c:160:2: error: (near initialization for 'decpair[1]')
        ...
      
      I'm not entirely sure what those errors mean, but I don't see them on
      gcc 4.8.  So let's consider gcc 4.8 to be the official starting point
      for __builtin_bswap16().
      
      Arnd Bergmann adds:
       "I found the commit in gcc-4.8 that replaced the powerpc-specific
        implementation of __builtin_bswap16 with an architecture-independent
        one.  Apparently the powerpc version (gcc-4.6 and 4.7) just mapped to
        the lhbrx/sthbrx instructions, so it ended up not being a constant,
        though the intent of the patch was mainly to add support for the
        builtin to x86:
      
          https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52624
      
        has the patch that went into gcc-4.8 and more information."
      
      Fixes: 7322dd75 ("byteswap: try to avoid __builtin_constant_p gcc bug")

      Merge branch 'dsa-mv88e6xxx-monolithic' · e26522cd
      David S. Miller authored
      Vivien Didelot says:
      
      ====================
      net: dsa: mv88e6xxx: turn into monolithic driver
      
      This patchset merges all mv88e6* drivers supported by the shared
      mv88e6xxx code into a single mv88e6xxx DSA switch driver.
      
      Some flags are added to describe the capabilities of a switch model,
      such as the presence of a PPU, EEPROM, some old or new registers, etc.
      
      First these flags are used to conditionally support the same set of
      functions in every driver, then specific driver files are removed in
      favor of the common mv88e6xxx driver.
      
      Only the merge of driver specific setup code assumes a few differences.
      If these differences such as frames priorities are really needed for
      some models, they can easily be brought back in a future patch.
      
      Some inconsistencies might show up, such as the need for
      MV88E6XXX_FLAG_PPU and MV88E6XXX_FLAG_PPU_ACTIVE flags. But this
      patchset does not aim to fix them yet. A future patch can do that if
      they end up being unwanted.
      
      The patchset has been tested on interconnected 88E6352 and 88E6185.
      
      Changes v1 -> v2:
        - add missing MV88E6XXX_FLAG_EEPROM flag checks
        - remove a few remaining _ prefixes
        - remove MV88E6XXX_FLAG_CORE_TAG_TYPE which is a specific default
      
      Changes RFC -> v1:
        - introduce flags in a separate patch
        - do not refactor anything yet
        - do not add new functions prefixed with _
        - drop packet discarding and mentioned tested platforms
        - factorize family flags
        - update text for NET_DSA_MV88E6XXX Kconfig entry

      Vivien Didelot authored
      Now that all drivers support the same set of functions and the same
      setup code, drop every model-specific DSA switch driver and replace them
      with a common mv88e6xxx driver.
      
      This merges the info tables into one, removes the function exports, the
      model-specific files, and update the defconfigs.
