stateless and stateful modes

Hello, I’m working on some bug that related to ethernet_interface  under phosphor-network and want to ensure everything is done correctly:  When systemd-networkd operates in stateless mode (IPv6AcceptRA = true), should the DHCP6 be disabled?  When systemd-networkd is in stateful mode (IPv6AcceptRA = false), should the DHCP6 be enabled?  In either scenario, should DHCP4 be impacted?
