I've used the NetBSD hifn driver with Soekris VPN1401 (actually a hifn
7955 chip inside) and the driver worked fine under heavy loads for short
periods of time (benchmarking).

Of course, only encryption works. The driver has an off by twelve bug
when it reads the result of any hash operation (it adds 12 bytes to a
pointer before the callback, and adds twelve again inside of the
callback). I sent a patch that fixes this to the list a few months ago.
