link_radv_enabled() and link_ndisc_enabled() use link_ipv6ll_enabled_harder(), which considers a static fe80:: address in [Address] sufficient to run radv/ndisc even when LinkLocalAddressing= (or IPv6LinkLocalAddressGenerationMode=none, which network_verify() folds into the same flag) disables the kernel-generated link-local. network_adjust_radv()/ndisc()/dhcp() however only check the raw link_local flag and zero router_prefix_delegation / ndisc / dhcp&IPV6 at parse time, so the runtime gate never gets a chance to fire. Factor the static-LL lookup out of link_ipv6ll_enabled_harder() into a Network-level helper and use it in the three network_adjust_*() functions, bringing parse-time and runtime behaviour in line.
