Pull networking fixes from David Miller:

 1) Fix memory leak in ieee80211_prep_connection(), sta_info leaked on
    error.  From Eytan Lifshitz.

 2) Unintentional switch case fallthrough in nft_reject_inet_eval(),
    from Patrick McHardy.

 3) Must check if payload lenth is a power of 2 in
    nft_payload_select_ops(), from Nikolay Aleksandrov.

 4) Fix mis-checksumming in xen-netfront driver, ip_hdr() is not in the
    correct place when we invoke skb_checksum_setup().  From Wei Liu.

 5) TUN driver should not advertise HW vlan offload features in
    vlan_features.  Fix from Fernando Luis Vazquez Cao.

 6) IPV6_VTI needs to select NET_IPV_TUNNEL to avoid build errors, fix
    from Steffen Klassert.

 7) Add missing locking in xfrm_migrade_state_find(), we must hold the
    per-namespace xfrm_state_lock while traversing the lists.  Fix from
    Steffen Klassert.

 8) Missing locking in ath9k driver, access to tid->sched must be done
    under ath_txq_lock().  Fix from Stanislaw Gruszka.

 9) Fix two bugs in TCP fastopen.  First respect the size argument given
    to tcp_sendmsg() in the fastopen path, and secondly prevent
    tcp_send_syn_data() from potentially using order-5 allocations.
    From Eric Dumazet.

10) Fix handling of default neigh garbage collection params, from Jiri
    Pirko.

11) Fix cwnd bloat and over-inflation of RTT when transmit segmentation
    is in use.  From Eric Dumazet.

12) Missing initialization of Realtek r8169 driver's statistics
    seqlocks.  Fix from Kyle McMartin.

13) Fix RTNL assertion failures in 802.3ad and AB ARP monitor of bonding
    driver, from Ding Tianhong.

14) Bonding slave release race can cause divide by zero, fix from
    Nikolay Aleksandrov.

15) Overzealous return from neigh_periodic_work() causes reachability
    time to not be computed.  Fix from Duain Jiong.

16) Fix regression in ipv6_find_hdr(), it should not return -ENOENT when
    a specific target is specified and found.  From Hans Schillstrom.

17) Fix VLAN tag stripping regression in BNA driver, from Ivan Vecera.

18) Tail loss probe can calculate bogus RTTs due to missing packet
    marking on retransmit.  Fix from Yuchung Cheng.

19) We cannot do skb_dst_drop() in iptunnel_pull_header() because
    multicast loopback detection in later code paths need access to
    skb_rtable().  Fix from Xin Long.

20) The macvlan driver regresses in that it propagates lower device
    offload support disables into itself, causing severe slowdowns when
    running over a bridge.  Provide the software offloads always on
    macvlan devices to deal with this and the regression is gone.  From
    Vlad Yasevich.

+- compatible: Should be "opencores,ethoc".
+- reg: two memory regions (address and length),
