The e1000 has VLAN acceleration. The VLAN tag is sent in a separate
register. If you do packet capture on the sender, the packet will
likely look 60 bytes long, even if it is 64 bytes on the wire.

The same thing happens on receive. Packet dumping with VLAN's is a bit
of a mess in Linux. If you're lucky you can find a card without VLAN
acceleration to do the packet dump.
