I'm not familar w/ netgraph, but it looks like you might be able to
do something simlar w/ ng_vlan and ng_bridge? Though bridge could be
replaced w/ one2many, or hub depending upon requirements... Also, is
this purely for snooping traffic? or do you want to be able to pass
traffic both ways?

Not sure if this is exactly what you want, but I think it would...
Though I don't know if you tried this, since you didn't describe
anything you tried...
