SKB's can be paged, in fact many devices already work by chopping
up lists of pages that the driver gives to the card.  NIU is one
of several examples.

The only difference between what a device like NIU is doing now and
what I propose is smart determination of at what offset and into
which buffers to do the demarcation.
