Well, then somebody needs to tell the IEEE folks that they should yank it out o
f the standard. There are two schools of thought about MAC addresses. It belo
ngs to the NIC, or it belongs to the machine. Sun took the latter approach, th
at's all.
Normally, you would hook up the quad card on four different subnets which would
cause no harm. If you have two machines sharing the same MAC addresses, they
will stomp on each other's traffic. This will cause the TCP stack to reject a
particular flow since the sequence numbers and acks will not line up.
