Ebtables can't help you with tc since they are quite unrelated. If you
can do what you want using iptables then there's hope for you since
someone recently wrote a patch to support ipv4 encapsulated in pppoe. If
you need tc, then the tc code needs to be altered which will probably be
not so easy (I don't know the tc implementation though).
