yoshfuji points out that sk_bound_dev_if should only be provided
for link-local addresses.
IPv6 getpeer/sockname also has this test, i.e. we will now
only set sin6_scope_id if the original(!) destination
was a link-local address.

userspace can query the original ipv4 destination address of a REDIRECTed
connection via
getsockopt(m_sock, SOL_IP, SO_ORIGINAL_DST, &m_server_addr, &addrsize)
but for ipv6 no such option existed.
This adds getsockopt(..., IPPROTO_IPV6, IP6T_SO_ORIGINAL_DST, ...).
Without this, userspace needs to parse /proc or use ctnetlink, which
appears to be overkill.
This uses option number 80 for IP6T_SO_ORIGINAL_DST, which is spare,
to use the same number we use in the IPv4 socket option SO_ORIGINAL_DST.

The kernel uses some default metric when routes are managed. For example, a
static route added with a metric set to 0 is inserted in the kernel with
metric 1024 (IP6_RT_PRIO_USER).
It is useful for routing daemons to know these values, to be able to set routes
without interfering with what the kernel does.

This patch re-enables Energy Detect Power Down (EDPD) mode for the
LAN8710/LAN8720. EDPD mode was disabled in a previous commit,
(b629820d18fa65cc598390e4b9712fd5f83ee693), because it was causing the
PHY to not be able to detect a link when cold started without a cable
connected.
The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of
each other in order to set the ENERGYON bit and exit EDPD mode. If a
link partner does send the pulses within this interval, the PHY will
remained powered down.
This workaround will manually toggle the PHY on/off upon calls to
read_status in order to generate link test pulses if the link is down.
If a link partner is present, it will respond to the pulses, which will
cause the ENERGYON bit to be set and will cause the EDPD mode to be
exited.

I have encountered several systems that have an invalid tag map. This
invalid tag map results in only two tags being generated 0x1F which is
usually applied to the first core in a Hyper-threaded pair and 0x00 which
is applied to the second core in a Hyper-threaded pair. The net result of
all this is that DCA causes significant cache thrash because the 0x1F tag
will send traffic to the second socket, which the 0x00 tag will not DCA tag
the frame resulting in no benefit.
For now the best solution from the driver's perspective is to just disable
DCA if the tag map is invalid. The correct solution for this would be to
have the BIOS on affected systems updated so that the correct tags are
generated for a given APIC ID.

nla_*() functions were used.
It also fix a sparse warning about a flag test (field i_flags). This field is
used in this file like a local flag only, so it is more an u16 (gre uses it as a
be16). This sparse warning was already there before the patch that add netlink

This patch allows clients to roam multiple times within the same
originator-interval.
To enable this new feature two key aspects that have been introduced:
1) packets are always directed to the node that was originally
serving the roamed client which will then re-route the data
to the correct destination at any point in time;
2) the client flags handling mechanism has been properly modified
in order to allow multiple roamings withinin the same orig-int.
Therefore flags are now set properly even in this scenario.

tt_poss_change is a node-wide flag which tells whether the node is in a roaming
state (a client recently moved to/away from it) in order to let it apply special
re-routing rules. However this flag does not give a clear idea of the current
state because it is not possible to understand *which client* is actually
involved in the roaming. For this reason a better approach has been chosen:
instead of using a node-wide variable, the roaming state is now given by a
per-tt_entry ROAM flag which, in case of packet coming through the node, tells
the node whether the real destination is in roaming state or not.
With this flag change, batadv_check_unicast_ttvn() has also been rearranged in
order to better fit the new re-routing logic and to be much more readable.

the initial bridge loop avoidance announcement packets may be lost. This
may lead to problems in finding other backbone gws, and therfore create
loops in the startup time.
