tw_cookie_values is never used in the TCP-stack.
It was added by 435cf559f (TCPCT part 1d: define TCP cookie option,
extend existing struct's), but already at that time it was not used at
all, nor mentioned in the commit-message.

Similar to iptunnel_xmit(), group these operations into a
helper function.
This by the way fixes the missing u64_stats_update_begin()
and u64_stats_update_end() for 32 bit arch.

With recent patches from Pravin, most tunnels can't use iptunnel_xmit()
any more, due to ip_select_ident() and skb->ip_summed. But we can just
move these operations out of iptunnel_xmit(), so that tunnels can
use it again.
This by the way fixes a bug in vxlan (missing nf_reset()) for net-next.

Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM
messages is unnecessary as there is already a dump_stack
after allocation failures.
Other trivial changes around these removals:
Convert a few comparisons of pointer to 0 to !pointer.
Change flow to remove unnecessary label.
Remove now unused variable.

Adds generic tunneling offloading support for IPv4-UDP based
tunnels.
GSO type is added to request this offload for a skb.
netdev feature NETIF_F_UDP_TUNNEL is added for hardware offloaded
udp-tunnel support. Currently no device supports this feature,
software offload is used.
This can be used by tunneling protocols like VXLAN.

This patch requires multicast interface-scoped addresses to supply a
sin6_scope_id. Because the sin6_scope_id is now also correctly used
in case of interface-scoped multicast traffic this enables one to use
interface scoped addresses over interfaces which are not targeted by the
default multicast route (the route has to be put there manually, though).
getsockname() and getpeername() now return the correct sin6_scope_id in
case of interface-local mc addresses.

__ipv6_addr_needs_scope_id checks if an ipv6 address needs to supply
a 'sin6_scope_id != 0'. 'sin6_scope_id != 0' was enforced in case
of link-local addresses. To support interface-local multicast these
checks had to be enhanced and are now consolidated into these new helper
functions.

Jeff Kirsher says:
====================
This series contains updates to ixgbevf and e1000e.
Alex's ixgbevf patch is meant to address several race issues that become
possible because next_to_watch could possibly be set to a value that shows
that the descriptor is done when it is not. In order to correct that we
instead make next_to_watch a pointer that is set to NULL during cleanup,
and set to the eop_desc after the descriptor rings have been written.
Stephen's ixgbevf patch makes the PCI id table a const and reformats the
table to match what the ixgbe driver does.
The remaining 13 patches from Bruce are cleanup patches for e1000e to
resolve checkpatch.pl warnings/errors, removing blank lines where
necessary and fix code formatting.

Split the vSockets header into kernel and UAPI parts. The former gets the bits
that used to be in __KERNEL__ guards, while the latter gets everything that is
user-visible. Tested by compiling vsock (+transport) and a simple user-mode

next_to_watch a pointer that is set to NULL during cleanup, and set to the

To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit. In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.
