I'm seeing some wierd behavior . . I'm playing with link layer packets
(802.3 frames).  When I send 18 bytes on one machine (and verify with
ethereal that 18 bytes leave, 60-70 bytes arrive on another interface on the
segment.  I've verified this behavior across both switches and hubs.

So, perhaps I'm misunderstanding 802.3.  Do link layer packets sometimes
just carry extra garbage that needs to be truncated by looking at a length
field in the packet?
