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

Pull networking fixes from David Miller:

 1) The wireless rate info fix from Johannes Berg.

 2) When a RAW socket is in hdrincl mode, we need to make sure that the
    user provided at least a minimally sized ipv4/ipv6 header. Fix from
    Alexander Potapenko.

 3) We must emit IFLA_PHYS_PORT_NAME netlink attributes using
    nla_put_string() so that it is NULL terminated.

 4) Fix a bug in TCP fastopen handling, wherein child sockets
    erroneously inherit the fastopen_req from the parent, and later can
    end up derefencing freed memory or doing a double free. From Eric
    Dumazet.

 5) Don't clear out netdev stats at close time in tg3 driver, from
    YueHaibing.

 6) Fix refcount leak in xt_CT, from Gao Feng.

 7) In nft_set_bitmap() don't leak dummy elements, from Liping Zhang.

 8) Fix deadlock due to taking the expectation lock twice, also from
    Liping Zhang.

 9) Make xt_socket work again with ipv6, from Peter Tirsek.

10) Don't allow IPV6 to be used with IPVS if ipv6.disable=1, from Paolo
    Abeni.

11) Make the BPF loader more flexible wrt. changes to the bpf MAP entry
    layout. From Jesper Dangaard Brouer.

12) Fix ethtool reported device name in aquantia driver, from Pavel
    Belous.

13) Fix build failures due to the compile time size test not working in
    netfilter conntrack. From Geert Uytterhoeven.
