The MultiCast Test require the NIC must support at least 256 multi-cast
group and
could receive the multi-cast packet it is set exactly!
Some of the NIC have some internal memory that could store the multicast
groups, but the others
might use bit-mask filter so that it might receive some unexpected muticast
packets!!
The NE2000 is the later one, so it will receive more multi-cast than
expected.
To resolve this issue, you may add some code in recevice handler and use S/W
based filter to exam all of the multi-cast packet!
(This might cause some performance penalty!)
