So I keep seeing this being pushed as a problem with clients...  but 
isn't it the ONT that is bugged out and appending the extra data after 
the checksum is already there (as Bill Herrin points out)?

I know it's asking a lot to expect networking equipment vendors to fix 
their gear, but...

Unless I'm totally not understanding the bug, which is entirely (and 
likely).
