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

  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
