2b9164771e ipv6: adapt connect for repair move
This is work the same as for ipv4.

All other hacks about tcp repair are in common code for ipv4 and ipv6,
so this patch is enough for repairing ipv6 connections.

242a18d137 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:

====================
This pull request is intended for net-next and contains the following changes:

1) Remove a redundant check when initializing the xfrm replay functions,
   from Ulrich Weber.
2) Use a faster per-cpu helper when allocating ipcomt transforms,
   from Shan Wei.
3) Use a static gc threshold value for ipv6, simmilar to what we do
   for ipv4 now.
4) Remove a commented out function call.

f2fb4ab2a6 igb: Do not parse past IP header on fragments beyond the first
This change makes it so that only the first fragment in a series of fragments
will have the L4 header pulled.  Previously we were always pulling the L4
header as well and in the case of UDP this can harm performance since only the
first fragment will have the header, the rest just contain data which should
be left in the paged portion of the packet.

63d4a8f963 igb: No longer rely on APME to determine WoL settings
Historically, we've been using the APME bit to determine whether a device
supports wake on a given port or not. However, this bit specifies the
default wake setting, rather than the wake support. Change the behavior so
that we use a flag to keep the capabilities separate from the enablement
while meeting customer requirements.

b1ac1ef71b ixgbe: fdb: only allow NUD_PERM fdb entries
There was a bitwise operation error in the fdb_add block
that was only allowing FDB types that were not permanent.

This was the opposite of the intent because the hardware
never ages out address these are the _only_ type of addrs
that should be allowed.

This was missed because until recently iproute2 did not
set any bit for this by default. And our test code to
manage FDB entries on embedded devices similarly did not
set these bits.

I am going to chalk this up as a bug and fix it now.

This patch enables ethtool to correctly identify flow control (pause

f3444d8b35 ixgbe: remove needless queuing for L4 ptp packets
This patch removes the queuing that was previously done for L4 packets
as it is not needed. The filter does not provide functionality, and it
is possible that queue setup here could trample settings done else-where
in the driver. (for example it may use a queue which isn't setup.)
Setting of the queue is not required for hardware timestamping and could
have inadverdent side effects.

e022b956c1 batman-adv: Use packing of 2 for all headers before an ethernet header
All packet headers in front of an ethernet header have to be completely
divisible by 2 but not by 4 to make the payload after the ethernet header again
4 bytes boundary aligned.

A packing of 2 is necessary to avoid extra padding at the end of the struct
caused by a structure member which is larger than two bytes. Otherwise the
structure would not fulfill the previously mentioned rule to avoid the
misalignment of the payload after the ethernet header. It may also lead to
leakage of information when the padding it not initialized before sending.

004e86fc58 batman-adv: Fix broadcast duplist for fragmentation
If the skb is fragmented, the checksum must be computed on the
individual fragments, just using skb->data may fail on fragmented
data. Instead of doing linearizing the packet, use the new
batadv_crc32 to do that more efficiently- it should not hurt
replacing the old crc16 by the new crc32.

bb351ba0bb batman-adv: Add wrapper to look up neighbor and send skb
By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate
code that looks up the next hop and then calls batadv_send_skb_packet().

Furthermore, this prepares the upcoming new implementation of
fragmentation, which requires the next hop to route packets.

Please note that this doesn't entirely remove the next-hop lookup in
routing.c and unicast.c, since it is used by the current fragmentation
code.

Also note that the next-hop info is removed from debug messages in
translation-table.c, since it is looked up elsewhere.

de4594a51c sctp: send abort chunk when max_retrans exceeded
In the event that an association exceeds its max_retrans attempts, we should

Because of the nature of the error, its unlikely to be received, but its a nice
clean way to close the association if it does make it through, and it will give

	+ route short-circuiting (aka L3 switching). Known destination IP
		addresses use the corresponding destination MAC address for
		switching rather than going to a (possibly remote) router first.
	+ netlink notification messages for forwarding table and L3 switching
		misses
