Pull networking fixes from David Miller:
 "Looks like a lot, but mostly driver fixes scattered all over as usual.

  Of note:

   1) Add conditional sched in nf conntrack in cleanup to avoid NMI
      watchdogs.  From Florian Westphal.

   2) Fix deadlock in nfnetlink cttimeout, also from Floarian.

   3) Fix handling of slaves in bonding ARP monitor validation, from Jay
      Vosburgh.

   4) Callers of ip_cmsg_send() are responsible for freeing IP options,
      some were not doing so.  Fix from Eric Dumazet.

   5) Fix per-cpu bugs in mvneta driver, from Gregory CLEMENT.

   6) Fix vlan handling in mv88e6xxx DSA driver, from Vivien Didelot.

   7) bcm7xxx PHY driver bug fixes from Florian Fainelli.

   8) Avoid unaligned accesses to protocol headers wrt.  GRE, from
      Alexander Duyck.

   9) SKB leaks and other problems in arc_emac driver, from Alexander
      Kochetkov.

  10) tcp_v4_inbound_md5_hash() releases listener socket instead of
      request socket on error path, oops.  Fix from Eric Dumazet.

  11) Missing socket release in pppoe_rcv_core() that seems to have
      existed basically forever.  From Guillaume Nault.

  12) Missing slave_dev unregister in dsa_slave_create() error path,
      from Florian Fainelli.

  13) crypto_alloc_hash() never returns NULL, fix return value check in
      __tcp_alloc_md5sig_pool.  From Insu Yun.

  14) Properly expire exception route entries in ipv4, from Xin Long.

  15) Fix races in tcp/dccp listener socket dismantle, from Eric
      Dumazet.

  16) Don't set IFF_TX_SKB_SHARING in vxlan, geneve, or GRE, it's not
      legal.  These drivers modify the SKB on transmit.  From Jiri Benc.

  17) Fix regression in the initialziation of netdev->tx_queue_len.
      From Phil Sutter.

  18) Missing unlock in tipc_nl_add_bc_link() error path, from Insu Yun.

  19) SCTP port hash sizing does not properly ensure that table is a
      power of two in size.  From Neil Horman.

  20) Fix initializing of software copy of MAC address in fmvj18x_cs
      driver, from Ken Kawasaki"
