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) ipv6: restore the behavior of ipv6_sock_ac_drop() amd-xgbe: Enable interrupts for all management counters amd-xgbe: Treat certain counter registers as 64 bit greth: moved TX ring cleaning to NAPI rx poll func cnic : Cleanup CONFIG_IPV6 & VLAN check 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 ...
