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

Pull networking fixes from David Miller:
 "This fixes the most immediate fallout from yesterday's networking
  merge:

   1) sock_tx_timestamp() must not clear the passed in tx_flags, but
      rather add to them.  Fix from Eric Dumazet.

   2) The hyperv driver sendbuf region increase needs to be decreased
      slightly to handle older backends.  From KY Srinivasan.

   3) Fix RCU lockdep splats in netlink diag after recent hashing
      changes, from Thomas Graf.

   4) The new IPV6_FLOWLABEL was given a socket option number that
      overlapped with an existing IP6 tables one, breaking ip6_tables.
      Fixed by Pablo Neira Ayuso"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  netlink: hold nl_sock_hash_lock during diag dump
  tcp: md5: check md5 signature without socket lock
  net: fix USB network driver config option.
  net: reallocate new socket option number for IPV6_AUTOFLOWLABEL
  vmxnet3: fix decimal printf format specifiers prefixed with 0x
  net-timestamp: cumulative tcp timestamping fixes
  hyperv: Adjust the size of sendbuf region to support ws2008r2
  cxgb4: Fix for SR-IOV VF initialization
  net-timestamp: sock_tx_timestamp() fix
