However, it seems TAHI testing requires dhcp6c client to start in "Stateless Mode" in certain testcases. (RFC 3736). And I guess, almost all dhcp6c client allows end user to select the mode in which dhcp6c should be started. Then why ConnMan doesn't have that feature? Apart from this does dhcp6c of Connman support other features? Like, 1. temporary address 2. rapid-commit 3. dhcp6c on multiple interface 4. prefix delegation (with T1, T2) . . . > > > >> >> *2.
