14. OpenSSL Crypto Poll Mode Driver
This code provides the initial implementation of the openssl poll mode driver. All cryptography operations are using Openssl library crypto API. Each algorithm uses EVP interface from openssl API - which is recommended by Openssl maintainers.

14.2. Installation
To compile the OpenSSL PMD the openssl library must be installed. It will then be picked up by the Meson/Ninja build system.
To ensure that you have the latest security fixes it is recommended that you use version 1.1.1g or newer.
- 1.1.1g, 2020-Apr-21. https://www.openssl.org/source/
14.3. Initialization
User can use app/test application to check how to use this PMD and to verify crypto processing.
Test name is cryptodev_openssl_autotest. For asymmetric crypto operations testing, run cryptodev_openssl_asym_autotest.
To verify real traffic l2fwd-crypto example can be used with this command:
sudo ./<build_dir>/examples/dpdk-l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_openssl"
--vdev "crypto_openssl"-- -p 0x3 --chain CIPHER_HASH
--cipher_op ENCRYPT --cipher_algo AES_CBC
--cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
--iv 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:ff
--auth_op GENERATE --auth_algo SHA1_HMAC
--auth_key 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11

14.4. Limitations
- Maximum number of sessions is 2048.
- Chained mbufs are supported only for source mbuf (destination must be contiguous).
- Hash only is not supported for GCM and GMAC.
- Cipher only is not supported for GCM and GMAC.
