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.
Refactor ipsec-secgw.c, sa.c, ipsec.h and ipsec.c to create
sessions at startup to fix the issue of the first packet
being dropped for inline crypto.
The create_session() function is now called at initialisation in
sa_add_rules() which is called from sa_init().
The return code for add_rules is checked.
Calls to create_session() in other functions are dropped.
Add crypto_devid_fill() in ipsec-secgw.c
Add max_session_size() in ipsec-secgw.c
Add check_cryptodev_capability() in ipsec.c
Add check_cryptodev_aead_capability() in ipsec.c
Add create_sec_session() and create_crypto_session() in ipsec.c
The crypto_dev_fill() function has been added to find the
enabled crypto devices.
The max_session_size() function has been added to calculate memory
requirements.
The check_cryptodev_capability() and check_cryptodev_aead_capability()
functions have been added to check that the SA is supported by the
crypto device.
The create_session() function is refactored to use the
create_sec_session() and create_crypto_session() functions.
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 crypto_devid_fill()
and max_session_size() and to call session_pool_init() and
session_priv_pool_init().
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.
