> Inline crypto installs a flow rule in the NIC. 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.
> 
> Fixes: ec17993a145a ("examples/ipsec-secgw: support security offload")
> Fixes: d299106e8e31 ("examples/ipsec-secgw: add IPsec sample application")
