The last time I mesed with this, which was a year and a half ago, you didn't get h/w accel unless you specified the engine. I had to use patches that were flagged EXPERIMENTAL to get engine support in whatever it was I was toying with, and had to use that support to get it using hardware crypto. I'll see if I can find what it was I was messing with and try again :) -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
