v2:
- added union
v3:
- added entry into feature matrix
- added information to prog_guide
v4:
- fixed formatting
- fixed grammar

Asymmetric Sessionless Support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Currently asymmetric crypto framework does not support sessionless.
+Asymmetric crypto framework supports sessionless operations.
+
+Fields that should be set by user are:
+
+Member xform of struct rte_crypto_asym_op should point to the user created
rte_crypto_asym_xform.
+Note that this rte_crypto_asym_xform should be immutable for the lifetime of
associated crypto_op.
+
+Member sess_type of rte_crypto_op should be set to RTE_CRYPTO_OP_SESSIONLESS.
