Comment 26 for bug 1631474

Hi,
I think the right way to fix this regression would have been to revert the change.
The change made in bug 1628306 made fairly wide spread changes. It caused this regression as seen, but also added behavioral changes.

Previously, 'ip=dhcp' would do a ipv4 dhcp request (via ipconfig).
The change was:
a.) to make it use dhclient
b.) to *also* do a dhcpv6 request in all cases.
