Nope, the patch displays mc list and filters bits only if not
promiscuous and not allmulti (normal ethernet mode)

If promiscuous -> a special PROMISC bit is selected on NIC (no display)
If allmulti -> all 128 bits are set (but not displayed in my patch)

I wanted to make sure the correct list of mc addrs is handled on your
machine. It seems to be the case, so there might be a hardware problem
with the multicast rx on this particular NIC
