Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) nfnetlink timestamp taken from wrong skb, fix from Florian Westphal.
2) Revert some msleep conversions in rtlwifi as these spots are in
atomic context, from Larry Finger.
3) Validate that NFTA_SET_TABLE attribute is actually specified when we
call nf_tables_getset(). From Phil Turnbull.
4) Don't do mdio_reset in stmmac driver with spinlock held as that can
sleep, from Vincent Palatin.
5) sk_filter() does things other than run a BPF filter, so we should
not elide it's call just because sk->sk_filter is NULL. Fix from
Eric Dumazet.
6) Fix missing backlog updates in several packet schedulers, from Cong
Wang.
7) bnx2x driver should allow VLAN add/remove while the interface is
down, from Michal Schmidt.
8) Several RDS/TCP race fixes from Sowmini Varadhan.
9) fq_codel scheduler doesn't return correct queue length in dumps,
from Eric Dumazet.
10) Fix TCP stats for tail loss probe and early retransmit in ipv6, from
Yuchung Cheng.
11) Properly initialize udp_tunnel_socket_cfg in l2tp_tunnel_create(),
from Guillaume Nault.
12) qfq scheduler leaks SKBs if a kzalloc fails, fix from Florian
Westphal.
13) sock_fprog passed into PACKET_FANOUT_DATA needs compat handling,
from Willem de Bruijn.
