Currently all the conntrack lookups are done using default zone.
In case the skb has a ct attached (e.g. template) we should use this zone
for lookups instead. This makes connlimit work with connections assigned
to other zones.

In case of OOM, there's nothing userspace can do.
If there's no room to put the payload in __build_packet_message(),
jump to nla_put_failure which already performs the corresponding
error reporting.

====================
The single patch in this series fixes some minor fallout from adding
support IPv6 real servers in IPv4 virtual-services and vice versa.
It should not have any run-time affect other than perhaps saving a few cycles.

Currently, despite the comment right before the function,
nf_log_register allows registering two loggers on with the same type and
end up overwriting the previous register.
Not a real issue today as current tree doesn't have two loggers for the
same type but it's better to get this protected.
Also make sure that all of its callers do error checking.

if dest is non-NULL, so this additional assignment is just confusing for

Compile the s390 10GB ethernet device driver only when
ETHERNET has been defined in the kernel configuration file.
Right now the qeth device driver is always built regardless
of which network connectivity is active.
