No, forcing on the IFF_ALLMULTI flag during driver initialization
is a good enough workaround for now (assuming the driver actually
programs the RX filter correctly in all-multicast mode).
ifp->if_flags = IFF_BROADCAST | IFF_SIMPLEX | IFF_MULTICAST;
ifp->if_flags |= IFF_ALLMULTI; /* Add me */
It's still a hack, but less of a hack than putting the interface in
promisc mode.
