22c352195e ipv6: remove superfluous nla_data() NULL pointer checks
nla_data() cannot return NULL, so these NULL pointer checks are
superfluous.

6aed0c8bf7 tunnel: use iptunnel_xmit() again
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.

720a43efd3 drivers:net: Remove unnecessary OOM messages after netdev_alloc_skb
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.
Hoist assignment from if.

842df07397 ipv6: use newly introduced __ipv6_addr_needs_scope_id and ipv6_iface_scope_id
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.

v2:
a) rebased ontop of patch 1/4 (now uses ipv6_addr_props)

v3:
a) reverted changes for ipv6_addr_props

v4:
a) unchanged

__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

checks had to be enhanced and are now consolidated into these new helper
functions.

v2:
a) migrated to struct ipv6_addr_props

v3:
a) reverted changes for ipv6_addr_props
b) test for address type instead of comparing scope

v4:

0bcf6aa72b Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
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.

e757e3e198 ixgbevf: Make next_to_watch a pointer and adjust memory barriers to avoid races
This change 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.

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.

f3564b2bb5 Merge branch 'tg3'
Nithin Nayak says:

====================
For the 57766 devices with no NVRAM, there is not enough space for the complete
boot code with EEE support. On these devices, the tg3 driver has to download
a service patch firmware to the scratchpad for the boot code to execute. This
patchset adds support to do the above.

A major portion of this patchset is refactoring the existing firmware download
section to allow a cleaner merge of the 57766 download. The 57766 firmware
differs from previous firmware in that it's not written to a contiguous area in
memory. It consists of multiple fragments to be written to different locations.
The patchset makes an attempt to make the new firmware format to be an
extension of the existing format.
