Getting IPv6 working with NetworkManager

[survient]

I'm trying to get this working on a regular Linux box(Fedora) and while IPv4 is working just fine I just can't seem to get ipv6 working. The eap_proxy script starts right up and in debug mode I can see the requests from the gateway coming through. All the dhcp4 requests are coming through successfully but complete silence when it comes to dhcpv6. I've cloned the MAC address of the gateway and set the DUID to what I believe is appropriate but no dice. NetworkManager allows you to set the duid to an absolute value if provided in hex. Doing a tcpdump on the interface connected to my BGW210-700 I get:

Client-ID Option 61, length 32: hardware-type 255, 00:00:00:01:00:02:00:00:0d:e9:30:30:31:45:34:36:2d: and I've tried setting the DUID both with the 00:00:00:01 prefix and without it to no avail. I don't think it's necessarily an issue with NetworkManager but rather some config setting I'm getting wrong. When I have the gateway in front of my routing device it gets all the IPv6 information just fine and allows SLAAC through plus gets the DHCPv6-PD magic going on the LAN interface.

I'm pretty sure if I wait 2 weeks for the lease to expire it would all start working but I'm haven't been able to figure out where to check the lease expiration on the gateway device itself.

Perhaps the README in my PR would help?
