Pull networking fixes from David Miller:
1) Fix skb leak in mac802154, from Martin Townsend
2) Use select not depends on NF_NAT for NFT_NAT, from Pablo Neira
Ayuso
3) Fix union initializer bogosity in vxlan, from Gerhard Stenzel
4) Fix RX checksum configuration in stmmac driver, from Giuseppe
CAVALLARO
5) Fix TSO with non-accelerated VLANs in e1000, e1000e, bna, ehea,
i40e, i40evf, mvneta, and qlge, from Vlad Yasevich
6) Fix capability checks in phy_init_eee(), from Giuseppe CAVALLARO
7) Try high order allocations more sanely for SKBs, specifically if a
high order allocation fails, fall back directly to zero order pages
rather than iterating down one order at a time. From Eric Dumazet
8) Fix a memory leak in openvswitch, from Li RongQing
9) amd-xgbe initializes wrong spinlock, from Thomas Lendacky
10) RTNL locking was busted in setsockopt for anycast and multicast, fix
from Sabrina Dubroca
11) Fix peer address refcount leak in ipv6, from Nicolas Dichtel
12) DocBook typo fixes, from Masanari Iida
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (101 commits)

net: treewide: Fix typo found in DocBook/networking.xml
bnx2x: Fix link problems for 1G SFP RJ45 module
3c59x: avoid panic in boomerang_start_xmit when finding page address:
netfilter: add explicit Kconfig for NETFILTER_XT_NAT
ipv6: use addrconf_get_prefix_route() to remove peer addr
ipv6: fix a refcnt leak with peer addr
net-timestamp: only report sw timestamp if reporting bit is set
drivers/net/fddi/skfp/h/skfbi.h: Remove useless PCI_BASE_2ND macros
l2tp: fix race while getting PMTU on PPP pseudo-wire
ipv6: fix rtnl locking in setsockopt for anycast and multicast
VMXNET3: Check for map error in vmxnet3_set_mc
openvswitch: distinguish between the dropped and consumed skb
amd-xgbe: Fix initialization of the wrong spin lock
openvswitch: fix a memory leak
netfilter: fix missing dependencies in NETFILTER_XT_TARGET_LOG
