Presumably for the Sparc and Alpha gear this kind of hardware would
be more common?

Yes, at least on the Sparc their most common 100baseT card checksums
TCP on receive and send. Currently the driver can only take advantage
of the checksums on receive, when a machanism is designed into the
stack to DMA TCP data directly from user pages, we can use the sending
checksum computation mechanism as well.
