slaacd ICMPv6 RA ND_OPT_ROUTE_INFO processing

[Filipe Mendonça]

Hello,

I've noticed that OpenBSD 7.1 slaacd isn't yet handling the Route
Information Option (ND_OPT_ROUTE_INFO) contained in the ICMPv6 router
advertisement messages.
In some use cases, this is desirable, so that the more specific routes get
automatically installed in the system routing table, as defined in RFC 4191.

The slaacd/engine.c code for handling the ND_OPT_ROUTE_INFO option is
currently in this state:

         case ND_OPT_ROUTE_INFO:
   #if 0
            log_debug("\tOption: %u (len: %u) not implemented",
                nd_opt_hdr->nd_opt_type, nd_opt_hdr->nd_opt_len *
                8);
   #endif
            break;


It's it possible to have some development in slaacd regarding this?

Thank you.
