+MACSEC Protocol
+~~~~~~~~~~~~~~~
+
+Media Access Control security (MACsec) provides point-to-point security on Ethernet
+links and is defined by IEEE standard 802.1AE. MACsec secures an Ethernet link for
+almost all traffic, including frames from the Link Layer Discovery Protocol (LLDP),
+Link Aggregation Control Protocol (LACP), Dynamic Host Configuration Protocol (DHCP),
+Address Resolution Protocol (ARP), and other protocols that are not typically secured
+on an Ethernet link because of limitations with other security solutions.

+
+To configure MACsec on an inline NIC device or a lookaside crypto device, a security
+association(SA) and a secure channel(SC) are created before creating rte_security
+session.
+
+SA is created using API ``rte_security_macsec_sa_create`` which allows setting
+SA keys, salt, SSCI, packet number(PN) into the PMD and the API returns a handle
+which can be used to map it with a secure channel using the API
+``rte_security_macsec_sc_create``. Same SAs can be used for multiple SCs.
+The Rx SC will need a set of 4 SAs for each of the association numbers(AN).
+For Tx SC a single SA is set which will be used by hardware to process the packet.
+
+The API ``rte_security_macsec_sc_create`` returns a handle for SC and this handle
+is set in ``rte_security_macsec_xform`` to create a MACsec session using
+``rte_security_session_create``.
