+For download and more details please visit `<https://github.com/01org/isa-l_crypto>`_.
In order to enable this virtual crypto PMD, user must:
-* Export the environmental variable AESNI_MULTI_BUFFER_LIB_PATH with the path where
- the library was extracted.
-* Build the multi buffer library (go to Installation section in AES-NI MB PMD documentation).
