Silly question I could probably figure out myself, but thought it would be
quicker to ask here...

When listening on an ethernet interface, are the packets you see from
yourself intercepted inside the network stack, or are you actually
sniffing them off the wire?  I'm helping someone track down corrupted
packets he's seeing in tcpdump, and I'd like to know if I can locate where
the corruption may be occuring more exactly.

Thanks,

Mike "Silby" Silbersack
