Wireshark-dev: [Wireshark-dev] How should we solve bug #2202

We have bug #2202 open for a problem where Wireshark is reporting an 
incorrect PPPoE payload length (as read from the PPPoE protocol data) 
when it is compared to the entire tvb length.  The problem is that there 
is an Ethernet trailer at the end that isn't being recognized as an 
Ethernet trailer.  One fix I have come up with is to call the 
tvb_set_reported_length() function to "chop off" the Ethernet trailer so 
the Ethernet dissector recognizes it as such.  However, this would 
defeat the check of PPPoE payload length vs. actual length available.  
Can anyone think of a better fix?


Thanks,
