End-to-end port-based eompls shouldn't care about tunneled PDUs coming in on a 
customer facing port, should it?

Or are you referring to a non-eompls environment on at least one of the 
customer-facing ends? (ie: dot1q-tunnel + forwarding | tunneling of whatever L2 
BPDUs might be supported by that port)
