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

Pull networking fixes from David Miller:

 1) Validate iov ranges before feeding them into iov_iter_init(), from
    Al Viro.

 2) We changed copy_from_msghdr_from_user() to zero out the msg_namelen
    is a NULL pointer is given for the msg_name.  Do the same in the
    compat code too.  From Catalin Marinas.

 3) Fix partially initialized tuples in netfilter conntrack helper, from
    Ian Wilson.

 4) Missing continue; statement in nft_hash walker can lead to crashes,
    from Herbert Xu.

 5) tproxy_tg6_check looks for IP6T_INV_PROTO in ->flags instead of
    ->invflags, fix from Pablo Neira Ayuso.

 6) Incorrect memory account of TCP FINs can result in negative socket
    memory accounting values.  Fix from Josh Hunt.

 7) Don't allow virtual functions to enable VLAN promiscuous mode in
    be2net driver, from Vasundhara Volam.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  netfilter: nft_compat: set IP6T_F_PROTO flag if protocol is set
  cx82310_eth: wait for firmware to become ready
  net: validate the range we feed to iov_iter_init() in sys_sendto/sys_recvfrom
  net: compat: Update get_compat_msghdr() to match copy_msghdr_from_user() behaviour
  be2net: use PCI MMIO read instead of config read for errors
  be2net: restrict MODIFY_EQ_DELAY cmd to a max of 8 EQs
  be2net: Prevent VFs from enabling VLAN promiscuous mode
  tcp: fix tcp fin memory accounting
  ipv6: fix backtracking for throw routes
  net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}
  ipv6: call ipv6_proxy_select_ident instead of ipv6_select_ident in udp6_ufo_fragment
  netfilter: xt_TPROXY: fix invflags check in tproxy_tg6_check()
  netfilter: restore rule tracing via nfnetlink_log
  netfilter: nf_tables: allow to change chain policy without hook if it exists
  netfilter: Fix potential crash in nft_hash walker
  netfilter: Zero the tuple in nfnl_cthelper_parse_tuple()
