[support] Unable to use Ubuntu /etc/network/interfaces script for interface configuration

[Martin André]

Hello Florian,

after some research we found out that this is actually a bug in ifupdown
package from ubuntu. They assume that IPv6 has been compiled as a module
and ifup command will fail if IPv6 support has been built in the kernel.

I've opened a bug in ubuntu bug tracker:
https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/158582

Regards,
Martin
