dbd_hardware_aes
exec master..dbd_hardware_aes @set=0|1
This function is obsolete. Now, most of CPUs use fast AES encryption instructions.
By default, hardware AES is ON if CPU supports it.
If you set the mode to 0, DbDefence will use the traditional (slower) CPU
instructions for AES. You can set @set=1 only if CPU supports
Intel AES-NI instructions.
