Missing Source-Routing Header in IPv6?

Hi,

as needed for the implementation for RPL non-storing mode in RIOT I was actually searching for Source-Routing-Header Option in IPv6. The search ended with no result - it finished in types.h in sys/net/include/sixlowpan/ where I think the other options are defined. Does anyone know whether the header option is implemented. Original RFC is 2460, a special version for RPL is RFC6554.

Thanks in advance Fabian
