Pull networking changes from David Miller:
 "The most important bit in here is the fix for input route caching from
  Eric Dumazet, it's a shame we couldn't fully analyze this in time for
  3.6 as it's a 3.6 regression introduced by the routing cache removal.

  Anyways, will send quickly to -stable after you pull this in.

  Other changes of note:

   1) Fix lockdep splats in team and bonding, from Eric Dumazet.

   2) IPV6 adds link local route even when there is no link local
      address, from Nicolas Dichtel.

   3) Fix ixgbe PTP implementation, from Jacob Keller.

   4) Fix excessive stack usage in cxgb4 driver, from Vipul Pandya.

   5) MAC length computed improperly in VLAN demux, from Antonio
      Quartulli."
