>Description:
le0 at 0x300-0x30f irq 10 maddr 0xc8000 msize 32768 on isa
le0: DE202 ethernet address 08:00:2b:3b:88:d0
this card and if_de driver doesnt receive ether multicast correctly,
it receive packet which is differ from what I intended.
It seems to be that multicast CRC table is wrong.
>How-To-Repeat:
Using mtest, add multicast address 33:33:0:0:0:1, it receive many ether multicast packet.
but it doesn't receive 33:33:0:0:0:1 at all.
