Pull networking fixes from David Miller:
"Mostly netfilter bug fixes in here, but we have some bits elsewhere as
well.
1) Don't do SNAT replies for non-NATed connections in IPVS, from
Julian Anastasov.
2) Don't delete conntrack helpers while they are still in use, from
Liping Zhang.
3) Fix zero padding in xtables's xt_data_to_user(), from Willem de
Bruijn.
4) Add proper RCU protection to nf_tables_dump_set() because we
cannot guarantee that we hold the NFNL_SUBSYS_NFTABLES lock. From
Liping Zhang.
5) Initialize rcv_mss in tcp_disconnect(), from Wei Wang.
6) smsc95xx devices can't handle IPV6 checksums fully, so don't
advertise support for offloading them. From Nisar Sayed.
7) Fix out-of-bounds access in __ip6_append_data(), from Eric
Dumazet.
8) Make atl2_probe() propagate the error code properly on failures,
from Alexey Khoroshilov.
9) arp_target[] in bond_check_params() is used uninitialized. This
got changes from a global static to a local variable, which is how
this mistake happened. Fix from Jarod Wilson.
10) Fix fallout from unnecessary NULL check removal in cls_matchall,
from Jiri Pirko. This is definitely brown paper bag territory..."
