Seems the libnfnetlink authors are a bit sloppy with respect to
licensing: the README file states:
"This library is released under GPLv2+."
After reading this I didn't check the sources.

The netfilter website also states different things:
http://www.netfilter.org/licensing.html mentions GPLv2 only
while http://www.netfilter.org/about.html#license says GPLv2+ only or
any later version.

I'll send a mail to the netfilter coreteam about this.

Best regards,
Thomas
