I haven't worked with that specific chipset, but I have tinkered with an
(ne2000 compatible) SMC 91C96.  I suspect that your chip will act much
the same.  By default, packets are not "received" into the on-board RAM
buffer area, unless the MAC address matches.  Consequently, it will not
generate any interrupts if the MAC doesn't match.  This behavior is
overriden by turning on promiscuous mode.  Then all packets heard by the
card will be copied to RAM (as long as the CRC is correct anyway, unless
of course you override the CRC setting).
