The nocache-argument was used in tcp_v4_send_synack as an argument to
inet_csk_route_req. However, since ba3f7f04 (ipv4: Kill
FLOWI_FLAG_RT_NOCACHE and associated code.) this is no more used.

This patch removes the unsued argument from tcp_v4_send_synack.

When attempting to change e.g. the advertising mask when the link is down
ecmd->speed is -1 causing mii_ethtool_sset() to bail out.

This bug bit when connecting to a gigabit switch through a 4-pin (industrial)
cable, since link negotiation would not complete (both endpoints claimed to
be gigabit-capable, but this is not possible with only 4 pins).
Any attempt to fix this by setting autonegation to not offer 1000Mbps
failed as the setting would not be accepted while the link was still down...

Set ecmd->speed to SPEED_1000 to satisfy mii_ethtool_sset()
(the actual value of ecmd->speed doesn't matter as long as it is valid,
since a re-negotation is forced afterwards).

* Remove tproxy core, now that we have socket early demux, from Florian

* A couple of patches to refactor conntrack event reporting to save a good

* Fix missing locking in NAT sequence adjustment, it did not manifested in

* Change sequence number adjustment variable to 32 bits, to delay the

* Comestic cleanups for IPVS, from Dragos Foianu.

* Fix possible null dereference in IPVS in the SH scheduler, from Daniel
  Borkmann.

* Allow to attach conntrack expectations via nfqueue. Before this patch, you
  had to use ctnetlink instead, thus, we save the conntrack lookup.

6lowpan: address uncompression fixes

The current implementation to uncompress addresses in a 6lowpan header
is completely broken.

This patch series fixes the parsing of addresses in a 6lowpan header.
It contains a major rewrite of the uncompress address function to parse
the address in a correct way.

Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone
(linux 6LoWPAN Stack) on the other side. The linux side contains all
possible addresses for the uncompression cases. Then I type a ping6 for
each case and lookup in wireshark and dmesg the correct reconstruction.

This patch drops the pre and postcount calculation from the
lowpan_uncompress_addr function.We use instead a switch/case
over address_mode value. The original implementation has several
bugs in this function and it was hard to decrypt how it works.
To make it maintainable and fix these bugs this patch basically
reimplements lowpan_uncompress_addr from scratch.

A list of bugs we found in the current implementation:

1) Properly support uncompression of short-address based IPv6 addresses
   (instead of basically copying garbage)

2) Fix use and uncompression of long-addresses based IPv6 addresses

3) Add missing ff:fe00 in the case of SAM/DAM = 2 and M = 0

This patch adds a helper function to parse the ipv6 header to a
6lowpan header in stream.

This function checks first if we can pull data with a specific
length from a skb. If this seems to be okay, we copy skb data to
a destination pointer and run skb_pull.

When a new 6lowpan fragment is received, a skbuff is allocated for
the reassembled packet. However when a 6lowpan packet compresses
link-local addresses based on link-layer addresses, the processing
function relies on the skb mac control block to find the related
link-layer address.

This patch copies the control block from the first fragment into
the newly allocated skb to keep a trace of the link-layer addresses
in case of a link-local compressed address.
