I repeatedly failed to get this right, so now I have to clean up my mess
afterwards.
Fixes: 7d6aadcd0a ("ip{,6}tunnel: have a shared stats parser/printer")

This has a slight side-effect of not aborting when /proc/net/dev is
malformed, but OTOH stats are not parsed for uninteresting interfaces.

Instead of duplicating the same code six times (key, ikey and okey in
iptunnel and ip6tunnel), have a common parsing routine. This has the
added benefit of having the same verbose error message in ip6tunnel as
well as iptunnel.
I'm not sure if parsing an IPv4 address as key makes sense for
ip6tunnel, but the code was there before so this patch at least doesn't
make it worse.

Make sure that return value of each socket() call is properly checked
and do not continue processing if the call failed.

This patch improves many error messages as follows:
- For incorrect parameters, show the value of the offending parameter, rather than just say that it is incorrect
- Rephrased messages for clarity
- Rephrased to more `mainstream' english

This patch fix two issues:
* If kernel is not supporting 6rd then ioctl() call
will return EINVAL, if so just skip perror call.
* 6rd scope is ipv6/ip tunnels. Dont try to fetch
6rd tunnel parms if tunnel protocol != IPPROTO_IPV6.

This patch provides iproute2 facilities to configure 6rd tunnel. To
configure a 6rd tunnel, you need to configure a sit tunnel and set
6rd prefix as following :
ip tunnel add sit1 mode sit local a.b.c.d ttl 64
ip tunnel 6rd dev sit1 6rd-prefix xxxx:yyyy::/z
Optionally you can provide a relay prefix :
ip tunnel 6rd dev sit1 6rd-relay_prefix e.f.g.h/i
Finally you can reset previous tunnel settings :
ip tunnel 6rd dev sit1 6rd-reset

Hi Stephen,
please review attached patch to add support for in-kernel potential router=
=20
lists for ISATAP tunnels.
Usage:
ip tunnel add name isatap0 mode isatap local 192.168.1.100
ip tunnel prl dev isatap0 prl-default 192.168.1.1
ip tunnel prl dev isatap0 prl-nodefault 192.168.1.2
ip tunnel prl dev isatap0 prl-delete 192.168.1.1
ip tunnel show # pr and pdr will be listed as well

Split common functions like ioctl to export them.
This is a preparation to support to configure IPv6-over-IPv6 tunnel.
This patch also includes minor improvemen:
o to stop to include unused headers
o to change function static if it is not needed to be exported
