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

Pull networking fixes from David Miller:

 1) Fix object leak on IPSEC offload failure, from Steffen Klassert.

 2) Fix range checks in ipset address range addition operations, from
    Jozsef Kadlecsik.

 3) Fix pernet ops unregistration order in ipset, from Florian Westphal.

 4) Add missing netlink attribute policy for nl80211 packet pattern
    attrs, from Peng Xu.

 5) Fix PPP device destruction race, from Guillaume Nault.

 6) Write marks get lost when BPF verifier processes R1=R2 register
    assignments, causing incorrect liveness information and less state
    pruning. Fix from Alexei Starovoitov.

 7) Fix blockhole routes so that they are marked dead and therefore not
    cached in sockets, otherwise IPSEC stops working. From Steffen
    Klassert.

 8) Fix broadcast handling of UDP socket early demux, from Paolo Abeni.
