Hi
Here's ugly patch against in 8.2-RELEASE (see attachment) that
makes vlan nesting possible.
# ifconfig em0.15 create
# ifconfig em0.15.18 create
Don't know about possible side effects though.
I suppose it doesn't play well wth bridges etc.
With ng_vlan nesting is also possible, but since 8.0
I had to comment out this node name check in ng_ether.c:
if ((node = ng_name2noderef(NULL, ifp->if_xname)) != NULL) {
NG_NODE_UNREF(node);
return;
Best regards,
Ivan
