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

Pull networking fixes from David Miller:

 1) Unbalanced refcounting in TIPC, from Jon Maloy.

 2) Only allow TCP_MD5SIG to be set on sockets in close or listen state.
    Once the connection is established it makes no sense to change this.
    From Eric Dumazet.

 3) Missing attribute validation in neigh_dump_table(), also from Eric
    Dumazet.

 4) Fix address comparisons in SCTP, from Xin Long.

 5) Neigh proxy table clearing can deadlock, from Wolfgang Bumiller.

 6) Fix tunnel refcounting in l2tp, from Guillaume Nault.

 7) Fix double list insert in team driver, from Paolo Abeni.

 8) af_vsock.ko module was accidently made unremovable, from Stefan
    Hajnoczi.

 9) Fix reference to freed llc_sap object in llc stack, from Cong Wang.

10) Don't assume netdevice struct is DMA'able memory in virtio_net
    driver, from Michael S. Tsirkin.
