No, we didn't see that behavior.
(Note that we did not use SNAP, in which case this behaviour would have 
been likely.)

We certainly need to expand our tests.  Right now, we only have half a 
dozen or so types of access points available for testing.

However, it is clear that any AP *should* forward LLC frames just fine.
The point of the testing can only be to find out about the failure 
modes of deployed APs and to make sure ROHC-over-802 is robust to these 
failure modes.

Gruesse, Carsten
