Reading the tulip manual (see below) triggered a question: When transmitting
a custom CRC, who is responsible for padding the frame to the minimum length?
If frame padding is left to the driver, what should be used for padding?

I (or rather, Google) found the tulip documentation at
<URL:http://www.intel.com/design/network/manuals/278074.htm>. The tulip
chips are capable of all these tricks too.
