I'm using tcpdump-3.8.2-10.RHEL4.
Maybe I just can't reproduce this bug because of race:
Packet should be changed before printing.

Quote:

I'm not sure I've understood, "usually packets are copied", does this mean, usually, tcpdump display the copied packet?

For not virtualized interfaces (e.g. when packets go from eth0 to eth1) packets are copied before changing MAC address. And tcpdump shows a copy of packet, which was not changed.
