Unfortunately openssl doesn't use the accelerator by default. This
means all apps that use openssl likewise are not automatically
accelerated. I suggested a patch but it was not accepted. I can't
recall how you force openssl and/or consumers to use the device.
If you want to check whether the kernel support is working correctly
look in src/tools/tools/crypto for cryptotest and hifnstats.
