Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:

 1) Really fix tuntap SKB use after free bug, from Eric Dumazet.

 2) Adjust SKB data pointer to point past the transport header before
    calling icmpv6_notify() so that the headers are in the state which
    that function expects.  From Duan Jiong.

 3) Fix ambiguities in the new tuntap multi-queue APIs.  From Jason
    Wang.

 4) mISDN needs to use del_timer_sync(), from Konstantin Khlebnikov.

 5) Don't destroy mutex after freeing up device private in mac802154,
    fix also from Konstantin Khlebnikov.

 6) Fix INET request socket leak in TCP and DCCP, from Christoph Paasch.

 7) SCTP HMAC kconfig rework, from Neil Horman.

 8) Fix SCTP jprobes function signature, otherwise things explode, from
    Daniel Borkmann.

 9) Fix typo in ipv6-offload Makefile variable reference, from Simon
    Arlott.

10) Don't fail USBNET open just because remote wakeup isn't supported,
    from Oliver Neukum.

11) be2net driver bug fixes from Sathya Perla.

12) SOLOS PCI ATM driver bug fixes from Nathan Williams and David
    Woodhouse.

13) Fix MTU changing regression in 8139cp driver, from John Greene.
