Harri,
possibly you have one of those ethernet cards with a neat driver that shifts the
checksum generation to the network adaptor itself? In that case on the level
captured with ethereal you will not be able to see any correct checksum since
it will be inserted once the frame was passed from the driver to the networking
hardware ... So there are two ways to get rid of these warnings, one is to
disable this check in ethereal, the other is deactivating this support in your
network adaptor driver (with a slight performance loss).
