vnode and a PC node, under normal circumstances, a real physical link is used. However, a user can use tb-set-multiplexed on the link that allows assign to map multiple vlinks over the same physical link. This is fine when the PC is running FBSD-STD which can use veth interfaces. Not so if it is running Linux or a non-standard BSD. This fix forces EMULATED links and VETH devices when the PC is running FBSD-STD and turns those attributes off otherwise so that assign will not give a mapping that cannot be realized on the client side. For the gory details of this problem, look at testbed-ops email thread "pcvm route problem" dated 29th Jan 2004. A problem still exists in the non-BSD router + jail vnodes in a delayed LAN. VLANs table is not getting the correct entries. A fix will come soon. Follow the testbed-ops email thread "fix for the pcvm route problem" dated 29th Jan 2004 for the gory details.
