+UADK Crypto Poll Mode Driver
+=======================================================
+
+UADK crypto PMD provides poll mode driver
+All cryptography operations are using UADK crypto API.
+Hardware accelerators using UADK are supposed to be supported.
+
+Features
+--------
+
+UADK crypto PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_AES_ECB``
+* ``RTE_CRYPTO_CIPHER_AES_CBC``
+* ``RTE_CRYPTO_CIPHER_AES_XTS``
+* ``RTE_CRYPTO_CIPHER_DES_CBC``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_MD5``
+* ``RTE_CRYPTO_AUTH_MD5_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA224``
+* ``RTE_CRYPTO_AUTH_SHA224_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA384``
+* ``RTE_CRYPTO_AUTH_SHA384_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA512``
+* ``RTE_CRYPTO_AUTH_SHA512_HMAC``
+
