Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) e1000e computes header length incorrectly wrt vlans, fix from Vlad
Yasevich.
2) ns_capable() check in sock_diag netlink code, from Andrew
Lutomirski.
3) Fix invalid queue pairs handling in virtio_net, from Amos Kong.
4) Checksum offloading busted in sxgbe driver due to incorrect
descriptor layout, fix from Byungho An.
5) Fix build failure with SMC_DEBUG set to 2 or larger, from Zi Shen
Lim.
6) Fix uninitialized A and X registers in BPF interpreter, from Alexei
Starovoitov.
7) Fix arch dependencies of candence driver.
8) Fix netlink capabilities checking tree-wide, from Eric W Biederman.
9) Don't dump IFLA_VF_PORTS if netlink request didn't ask for it in
IFLA_EXT_MASK, from David Gibson.
10) IPV6 FIB dump restart doesn't handle table changes that happen
meanwhile, causing the code to loop forever or emit dups, fix from
Kumar Sandararajan.
11) Memory leak on VF removal in bnx2x, from Yuval Mintz.
12) Bug fixes for new Altera TSE driver from Vince Bridgers.
13) Fix route lookup key in SCTP, from Xugeng Zhang.
14) Use BH blocking spinlocks in SLIP, as per a similar fix to CAN/SLCAN
driver. From Oliver Hartkopp.
15) TCP doesn't bump retransmit counters in some code paths, fix from
Eric Dumazet.
16) Clamp delayed_ack in tcp_cubic to prevent theoretical divides by
zero. Fix from Liu Yu.

John Fastabend.
18) Properly reference the transport module when vsock_core_init() runs,
from Andy King.
19) Fix buffer overflow in cdc_ncm driver, from Bjørn Mork.
20) IP_ECN_decapsulate() doesn't see a correct SKB network header in
ip_tunnel_rcv(), fix from Ying Cai.
