Most of them, actually.  The relevant piece of code should be  
illuminating:

 From sdp_inet.c:1461

         switch (optname) {
         case TCP_NODELAY:
                 conn->nodelay = value ? 1 : 0;

                 if (conn->nodelay > 0)
                         (void)sdp_send_flush(conn);

                 break;

         default:
                 sdp_warn("SETSOCKOPT unimplemented option <%d:%d>  
conn <%d>.",
                          level, optname, conn->hashent);
                 break;
         }

I think we should fail these all other options and not just print a  
warning and return.  Until we can characterize all of them.

So, set result to -ENOPROTOOPT instead of just breaking.
