Pull networking fixes from David Miller:

 1) ping_err() ICMP error handler looks at wrong ICMP header, from Li
    Wei.

 2) TCP socket hash function on ipv6 is too weak, from Eric Dumazet.

 3) netif_set_xps_queue() forgets to drop mutex on errors, fix from
    Alexander Duyck.

 4) sum_frag_mem_limit() can deadlock due to lack of BH disabling, fix
    from Eric Dumazet.

 5) TCP SYN data is miscalculated in tcp_send_syn_data(), because the
    amount of TCP option space was not taken into account properly in
    this code path.  Fix from yuchung Cheng.

 6) MLX4 driver allocates device queues with the wrong size, from Kleber
    Sacilotto.

 7) sock_diag can access past the end of the sock_diag_handlers[] array,
    from Mathias Krause.

 8) vlan_set_encap_proto() makes incorrect assumptions about where
    skb->data points, rework the logic so that it works regardless of
    where skb->data happens to be.  From Jesse Gross.

 9) Fix gianfar build failure with NET_POLL enabled, from Paul
    Gortmaker.

10) Fix Ipv4 ID setting and checksum calculations in GRE driver, from
   Pravin B Shelar.

11) bgmac driver does:

        int i;

        for (i = 0; ...; ...) {
                ...
                for (i = 0; ...; ...) {

    effectively corrupting the outer loop index, use a seperate
    variable for the inner loops.  From Rafał Miłecki.

12) Fix suspend bugs in smsc95xx driver, from Ming Lei.
