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
