Pull networking fixes from David Miller:

 1) Fix namespace init and cleanup in phonet to fix some oopses, from
    Eric W. Biederman.

 2) Missing kfree_skb() in AF_KEY, from Julia Lawall.

 3) Refcount leak and source address handling fix in l2tp from James
    Chapman.

 4) Memory leak fix in CAIF from Tomasz Gregorek.

 5) When routes are cloned from ipv6 addrconf routes, we don't process
    expirations properly.  Fix from Gao Feng.

 6) Fix panic on DMA errors in atl1 driver, from Tony Zelenoff.

 7) Only enable interrupts in 8139cp driver after we've registered the
    IRQ handler.  From Jason Wang.

 8) Fix too many reads of KS_CIDER register in ks8851 during probe,
    fixing crashes on spurious interrupts.  From Matt Renzelmann.

 9) Missing include in ath5k driver and missing iounmap on probe
    failure, from Jonathan Bither.

10) Fix RX packet handling in smsc911x driver, from Will Deacon.

11) Fix ixgbe WoL on fiber by leaving the laser on during shutdown.

12) ks8851 needs MAX_RECV_FRAMES increased otherwise the internal MAC
    buffers are easily overflown.  Fix from Davide Cimingahi.

13) Fix memory leaks in peak_usb CAN driver, from Jesper Juhl.

14) gred packet scheduler can dump in WRED more when doing a netlink
    dump.  Fix from David Ward.

15) Fix MTU in USB smsc75xx driver, from Stephane Fillod.

16) Dummy device needs ->ndo_uninit handler to properly handle
    ->ndo_init failures.  From Hiroaki SHIMODA.

17) Fix TX fragmentation in ath9k driver, from Sujith Manoharan.

18) Missing RTNL lock in ixgbe PM resume, from Benjamin Poirier.

19) Missing iounmap in farsync WAN driver, from Julia Lawall.

20) With LRO/GRO, tcp_grow_window() is easily tricked into not growing
    the receive window properly, and this hurts performance.  Fix from
    Eric Dumazet.

21) Network namespace init failure can leak net_generic data, fix from
    Julian Anastasov.

22) Fix skb_over_panic due to mis-accounting in TCP for partially ACK'd
    SKBs.  From Eric Dumazet.

23) New IDs for qmi_wwan driver, from Bjørn Mork.

24) Fix races in ax25_exit(), from Eric W. Biederman.

25) IPV6 TCP doesn't handle TCP_MAXSEG socket option properly, copy over
    logic from the IPV4 side.  From Neal Cardwell.
