You may not be able to do this without seriously hacking the driver itself -
if at all. In fact, have a look at the 802.3 headers you get from a normal
Ethernet capture. Note that the FCS field is (usually) missing. Most
Ethernet drivers/cards strip this off before the data is available to higher
layers.
