 The configuration structure reuses the ``rte_crypto_sym_xform`` struct for crypto related
 configuration. The ``rte_security_session_action_type`` struct is used to specify whether the
 session is configured for Lookaside Protocol offload or Inline Crypto or Inline Protocol
 Offload.

 Currently the library defines configuration parameters for IPsec and PDCP only.
 For other protocols like MACSec, structures and enums are defined as place holders
