Pull networking update from David Miller:

 1) Pairing and deadlock fixes in bluetooth from Johan Hedberg.

 2) Add device IDs for AR3011 and AR3012 bluetooth chips.  From
    Giancarlo Formicuccia and Marek Vasut.

 3) Fix wireless regulatory deadlock, from Eliad Peller.

 4) Fix full TX ring panic in bnx2x driver, from Eric Dumazet.

 5) Revert the two commits that added skb_orphan_try(), it causes
    erratic bonding behavior with UDP clients and the gains it used to
    give are mostly no longer happening due to how BQL works.  From Eric
    Dumazet.

 6) It took two tries, but Thomas Graf fixed a problem wherein we
    registered ipv6 routing procfs files before their backend data were
    initialized properly.

 7) Fix max GSO size setting in be2net, from Sarveshwar Bandi.

 8) PHY device id mask is wrong for KSZ9021 and KS8001 chips, fix from
    Jason Wang.

 9) Fix use of stale SKB data pointer after skb_linearize() call in
    batman-adv, from Antonio Quartulli.

10) Fix memory leak in IXGBE due to missing __GFP_COMP, from Alexander
    Duyck.

11) Fix probing of Gobi devices in qmi_wwan usbnet driver, from Bjørn
    Mork.

12) Fix suspend/resume and open failure handling in usbnet from Ming
    Lei.

13) Attempt to fix device r8169 hangs for certain chips, from Francois
    Romieu.

14) Fix advancement of RX dirty pointer in some situations in sh_eth
    driver, from Yoshihiro Shimoda.

15) Attempt to fix restart of IPV6 routing table dumps when there is an
    intervening table update.  From Eric Dumazet.

16) Respect security_inet_conn_request() return value in ipv6 TCP.  From
    Neal Cardwell.

17) Add another iPAD device ID to ipheth driver, from Davide Gerhard.

18) Fix access to freed SKB in l2tp_eth_dev_xmit(), and fix l2tp lockdep
    splats, from Eric Dumazet.

19) Make sure all bridge devices, regardless of whether they were
    created via netlink or ioctls, have their rtnetlink ops hooked up.
    From Thomas Graf and Stephen Hemminger.
