I have a driver written, but not debugged, and I don't really have
time to debug it at the moment. Maybe I should dust it off and
get back to it...

Well, the chip is very powerful -- it can do different buffer
rings for different packet sizes, does hardware vlan tagging,
priority queueing, checksum offloading, and has a "general
purpose packet processor" onboard, which presumably could be
coaxed into doing crypto processing.
But the downside is that it is a REAL pain to program. But that's
only annoying for the driver writer (in this case, me), of course.
