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.
