tahi tests RFC 3315 test cases 13 14 15 16 17 18 failure

     These test cases tests the 'DHCP Unique IDentifier' (DUID) sent in the solicitation message. This DUID is defined in RFC3315 section 9. There are three types of DUIDs (DUID-LLT, DUID-EN, DUID-LL). The device is free to choose its DUID format. Among the six test cases only two are supported by any kind of device. So other four will be always 'not yet supported'. You have choose which DUID should be used for your device. Find your device's DUID and set this in the 'config.pl' file.

     To find the type of DUID used by your device, capture DHCPv6 solicitation message sent by your device in wireshark. In that expand the DHCPv6 payload. There will be a section 'client identifier'. In that 'option type' and 'option length' are generic. Leave them and compare other elements with the DUID definitions given in RFC 3315. You will identify the type.
