This flow rule must be installed before the first inbound packet is received. The create_session() function installs the flow rule, create_session() has been refactored into create_inline_session() and create_lookaside_session(). The create_inline_session() function uses the socket_ctx data and is now called at initialisation in sa_add_rules(). The max_session_size() function has been added to calculate memory requirements. The cryprodev_init() function has been refactored to drop calls to rte_mempool_create() and to drop calculation of memory requirements. The main() function has been refactored to call max_session_size() and to call session_pool_init() and session_priv_pool_init() earlier. The ports are started now before adding a flow rule in main(). The sa_init(), sp4_init(), sp6_init() and rt_init() functions are now called after the ports have been started. The rte_ipsec_session_prepare() function is called in fill_ipsec_session() for inline which is called from the ipsec_sa_init() function.
