vtnet(4) is the only device that doesn't correctly support promiscuous mode? I don't know details of vtnet(4) but it seems it's not hard to mimic promiscuous mode. I'm not sure why the driver returns ENOTSUP to user land given that vtnet(4) defaults to promiscuous mode for backwards compatibility. It also does not handle multicast filter configuration when VTNET_FLAG_CTRL_RX flag is not set. If vtnet(4) does not support multicast filter, it shouldn't announce IFF_MULTICAST. I wonder how vtnet(4) can work with carp(4) given that its multicast handling is ignored. _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
