Pull networking updates from David Miller:

 1) Fix flexcan build on big endian, from Arnd Bergmann

 2) Correctly attach cpsw to GPIO bitbang MDIO drive, from Stefan Roese

 3) udp_add_offload has to use GFP_ATOMIC since it can be invoked from
    non-sleepable contexts.  From Or Gerlitz

 4) vxlan_gro_receive() does not iterate over all possible flows
    properly, fix also from Or Gerlitz

 5) CAN core doesn't use a proper SKB destructor when it hooks up
    sockets to SKBs.  Fix from Oliver Hartkopp

 6) ip_tunnel_xmit() can use an uninitialized route pointer, fix from
    Eric Dumazet

 7) Fix address family assignment in IPVS, from Michal Kubecek

 8) Fix ath9k build on ARM, from Sujith Manoharan

 9) Make sure fail_over_mac only applies for the correct bonding modes,
    from Ding Tianhong

10) The udp offload code doesn't use RCU correctly, from Shlomo Pongratz

11) Handle gigabit features properly in generic PHY code, from Florian
    Fainelli

12) Don't blindly invoke link operations in
    rtnl_link_get_slave_info_data_size, they are optional.  Fix from
    Fernando Luis Vazquez Cao

13) Add USB IDs for Netgear Aircard 340U, from Bjørn Mork

14) Handle netlink packet padding properly in openvswitch, from Thomas
    Graf

15) Fix oops when deleting chains in nf_tables, from Patrick McHardy

16) Fix RX stalls in xen-netback driver, from Zoltan Kiss

17) Fix deadlock in mac80211 stack, from Emmanuel Grumbach

18) inet_nlmsg_size() forgets to consider ifa_cacheinfo, fix from Geert
    Uytterhoeven

19) tg3_change_mtu() can deadlock, fix from Nithin Sujir

20) Fix regression in setting SCTP local source addresses on accepted
    sockets, caused by some generic ipv6 socket changes.  Fix from
    Matija Glavinic Pecotic

21) IPPROTO_* must be pure defines, otherwise module aliases don't get
    constructed properly.  Fix from Jan Moskyto

22) IPV6 netconsole setup doesn't work properly unless an explicit
    source address is specified, fix from Sabrina Dubroca

23) Use __GFP_NORETRY for high order skb page allocations in
    sock_alloc_send_pskb and skb_page_frag_refill.  From Eric Dumazet

24) Fix a regression added in netconsole over bridging, from Cong Wang

25) TCP uses an artificial offset of 1ms for SRTT, but this doesn't jive
    well with TCP pacing which needs the SRTT to be accurate.  Fix from
    Eric Dumazet

26) Several cases of missing header file includes from Rashika Kheria

27) Add ZTE MF667 device ID to qmi_wwan driver, from Raymond Wanyoike

28) TCP Small Queues doesn't handle nonagle properly in some corner
    cases, fix from Eric Dumazet

29) Remove extraneous read_unlock in bond_enslave, whoops.  From Ding
    Tianhong

30) Fix 9p trans_virtio handling of vmalloc buffers, from Richard Yao
