on the AES-NI code, and modified as needed for use on ARMv8. When loaded the driver will check the appropriate field in the id_aa64isar0_el1 register to see if AES is supported, and if so the probe function will signal the driver should attach. With this I have seen up to 2000Mb/s from the cryptotest test with a single thread on a ThunderX Pass 2.0.
