Pull networking fixes from David Miller:

 1) Don't halt the firmware in r8152 driver, from Hayes Wang.

 2) Handle full sized 802.1ad frames in bnx2 and tg3 drivers properly,
    from Vlad Yasevich.

 3) Don't sleep while holding tx_clean_lock in netxen driver, fix from
    Manish Chopra.

 4) Certain kinds of ipv6 routes can end up endlessly failing the route
    validation test, causing it to be re-looked up over and over again.
    This particularly kills input route caching in TCP sockets.  Fix
    from Hannes Frederic Sowa.

 5) netvsc_start_xmit() has a use-after-free access to skb->len, fix
    from K Y Srinivasan.

 6) Fix matching of inverted containers in ematch module, from Ignacy
    Gawędzki.

 7) Aggregation of GRO frames via SKB ->frag_list for linear skbs isn't
    handled properly, regression fix from Eric Dumazet.

 8) Don't test return value of ipv4_neigh_lookup(), which returns an
    error pointer, against NULL.  From WANG Cong.

 9) Fix an old regression where we mistakenly allow a double add of the
    same tunnel.  Fixes from Steffen Klassert.

10) macvtap device delete and open can run in parallel and corrupt lists
    etc., fix from Vlad Yasevich.

11) Fix build error with IPV6=m NETFILTER_XT_TARGET_TPROXY=y, from Pablo
    Neira Ayuso.

12) rhashtable_destroy() triggers lockdep splats, fix also from Pablo.
