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.
