Public bug reported:
In changes made under bug 1621615 (specifically a1cdebdea), we now
expect that there may be a 'ip6=' argument on the kernel command line.
The changes made did not test the case where there is 'ip6=' and no
'ip='.
The code currently will return with no network configuration found if
there is only ip6=...
