AFAIK, we're breaking IEEE Ethernet specifications by using jumbo 
frames (or, at the very least, using an unspecified features).  To me, 
that should imply it might be wise to err to the side of caution.

Note: it might be possible to do away with an extra roundtrip if 
that's issue, by adding some padding to the PPP/PPPoE messages 
themselves, instead of using separate PPP echo req/response.
