Description

On Mac OS X 10.5.8 with a primary NIC named en0 and a virtual NIC named vlan3 accessing tagged traffic on en0

Guest is linux, eth0 is bridged to vlan3

Sniffing traffic with tcpdump on both host (vlan3) and guest (eth0) shows that some of the packets reaching guest contains additional 4 bytes after source/dest MAC address replicating the last 4 bytes of the source MAC.
