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

Pull networking fixes from David Miller:

 1) OpenVswitch's lookup_datapath() returns error pointers, so don't
    check against NULL.  From Jiri Pirko.

 2) pfkey_compile_policy() code path tries to do a GFP_KERNEL allocation
    under RCU locks, fix by using GFP_ATOMIC when necessary.  From
    Nikolay Aleksandrov.

 3) phy_suspend() indirectly passes uninitialized data into the ethtool
    get wake-on-land implementations.  Fix from Sebastian Hesselbarth.

 4) CPSW driver unregisters CPTS twice, fix from Benedikt Spranger.

 5) If SKB allocation of reply packet fails, vxlan's arp_reduce() defers
    a NULL pointer.  Fix from David Stevens.

 6) IPV6 neigh handling in vxlan doesn't validate the destination
    address properly, and it builds a packet with the src and dst
    reversed.  Fix also from David Stevens.

 7) Fix spinlock recursion during subscription failures in TIPC stack,
    from Erik Hugne.

 8) Revert buggy conversion of davinci_emac to devm_request_irq, from
    Chrstian Riesch.

 9) Wrong flags passed into forwarding database netlink notifications,
    from Nicolas Dichtel.

10) The netpoll neighbour soliciation handler checks wrong ethertype,
    needs to be ETH_P_IPV6 rather than ETH_P_ARP.  Fix from Li RongQing.
