Linux 2.6 IPv6 interface "ip6tnl0"

Hope this posting is OK although I'm not on this list.

With Linux 2.6 IPv6 came a tunnel interface, "ip6tnl0".

It breaks the code that extracts interface #, since that algorithm
stops at the first digit and takes the rest as #, i.e. <ip><6tnl0>.

I think the "diff -c" below is an appropriate fix.
