  "Networking:

   A few straggler bug fixes:

   1) Fix indexing of multi-pass dumps of ipv6 addresses, from David
      Ahern.

   2) Revert RCU locking change for bonding netpoll, causes worse
      problems than it solves.

   3) pskb_trim_rcsum_slow() doesn't handle odd trim offsets, resulting
      in erroneous bad hw checksum triggers with CHECKSUM_COMPLETE
      devices.  From Dimitris Michailidis.

   4) a revert to some neighbour code changes that adjust notifications
      in a way that confuses some apps."

  Revert "neighbour: force neigh_invalidate when NUD_FAILED update is from admin"
  net/ipv6: Fix index counter for unicast addresses in in6_dump_addrs

  Revert "bond: take rcu lock in netpoll_send_skb_on_dev"
