[Bug 1397022] [NEW] Instances won't obtain additional configuration options from DHCP when using stateless DHCPv6 subnets

 

Public bug reported:

When additional DHCP configuration is available from DHCP server, radvd
should set Other flag in RAs. It's not done by L3 agent, so clients are
left unaware about additional configuration and don't spawn dhcp clients
to receive those. This results in e.g. DNS nameservers set for a subnet
not propagated into instance's /etc/resolv.conf, among other things.

** Affects: neutron
