ipv6: add special mode forwarding=2 to send RS while
[ upstream commit c3bccac2fa76f1619dfe4fb7b9bee69de7f066d8 ]
configured as router
Similar to accepting router advertisement, the IPv6 stack does not send router
solicitations if forwarding is enabled.
This patch enables this behavior to be overruled by setting forwarding to the
special value 2.
