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

Pull networking fixes from David Miller:
 "Several fixups, of note:

  1) Fix unlock of not held spinlock in RXRPC code, from Alexey
     Khoroshilov.

  2) Call pci_disable_device() from the correct shutdown path in bnx2x
     driver, from Yuval Mintz.

  3) Fix qeth build on s390 for some configurations, from Eugene
     Crosser.

  4) Cure locking bugs in bond_loadbalance_arp_mon(), from Ding
     Tianhong.

  5) Must do netif_napi_add() before registering netdevice in sky2
     driver, from Stanislaw Gruszka.

  6) Fix lost bug fix during merge due to code movement in ieee802154,
     noticed and fixed by the eagle eyed Stephen Rothwell.

  7) Get rid of resource leak in xen-netfront driver, from Annie Li.

  8) Bounds checks in qlcnic driver are off by one, from Manish Chopra.

  9) TPROXY can leak sockets when TCP early demux is enabled, fix from
     Holger Eitzenberger"
