[systemd-devel] [PATCH 03/24] sd-dhcp6-client: Add initial Router Advertisement test case

Fri Jun 13 06:44:53 PDT 2014
Feed a Router Advertisement to the code and expect proper events
each time. The sending part is ignored, as all of it is static code
in the real dhcp_network_icmp6_send_rs() function.
