No, not at the moment. IFF_POINTOPOINT and IFF_BROADCAST are opposites, so TUNSIFMODE can be used to undo what it's already done. In FreeBSD, IFF_MULTICAST is always there. In NetBSD there's SIOCADDMULTI and SIOCDELMULTI and in OpenBSD there's struct tuninfo's flags field (passed to TUNSIFINFO). I'd condone supporting SIOCADDMULTI and SIOCDELMULTI, and also having a flags field in struct tuninfo, but I don't know if this is a good idea on a more general level.... ie, should there really be two ways to do these things ? For the moment though, I think the documentation is right. > Index: tun.4 > =================================================================== > RCS file: /home/ncvs/src/share/man/man4/tun.4,v > retrieving revision 1.9 > diff -u -d -r1.9 tun.4 > --- tun.4 2000/03/06 07:08:14 1.9 > +++ tun.4 2000/03/07 12:37:25 > @@ -147,7 +147,10 @@ > its value must be either > .Dv IFF_POINTOPOINT > or > -.Dv IFF_BROADCAST . > +.Dv IFF_BROADCAST > +(optionally > +.Dv IFF_MULTICAST > +may be or'ed into the value). > The type of the corresponding > .Em tun Ns Sy n > interface is set to the supplied type.
