    That's probably the default of most chipsets, but I wonder if you could
    tell it to send the busted packets up the stack anyway. Then, the driver
    could make the decision in software whether or not to correct/foward, or
    discard the packet... I assume that in order to detect a CRC error,
    the NIC already has the packet in it's buffers somewhere...
