Are you sure that your router advertisement daemon is running (radvd on Linux) and handing out a proper IPv6 subnet? That is required as far as I know for your DHCPv6 server to be used for either address or PXE options to be delivered.

Also check the counters (ifstat) to ensure that you're actually receiving responses to your configuration requests. Worst case scenario you can try to configure a static address and route to verify if the issue is RA or DHCPv6 responses. Also try to build with debug enabled for dhcp and RA. Find the .c file which contains the code you're unsure if works and add DEBUG=dhcp,slaac to the make command line if your .c files are named dhcp.c and slaac.c.
