threads and supports inline protocol only.** It also provides infrastructure for
non-internal port however does not define any worker threads.
+ Event mode also supports event vectorization. The event devices, ethernet device
+ pairs which support the capability ``RTE_EVENT_ETH_RX_ADAPTER_CAP_EVENT_VECTOR`` can
+ aggregate packets based on flow characteristics and generate a ``rte_event``
+ containing ``rte_event_vector``.
+ The aggregation size and timeout can be given using command line options vector-size
+ (default vector-size is 16) and vector-tmo (default vector-tmo is 102400ns).
+ By default event vectorization is disabled and it can be enabled using event-vector
+ option.
+
Additionally the event mode introduces two submodes of processing packets:
* Driver submode: This submode has bare minimum changes in the application to support
* No IPv6 options headers.
* No AH mode.
-* Supported algorithms: AES-CBC, AES-CTR, AES-GCM, 3DES-CBC, HMAC-SHA1 and NULL.
+* Supported algorithms: AES-CBC, AES-CTR, AES-GCM, 3DES-CBC, HMAC-SHA1,
+ AES-GMAC, AES_CTR, AES_XCBC_MAC, AES_CCM, CHACHA20_POLY1305 and NULL.
* Each SA must be handle by a unique lcore (*1 RX queue per port*).
Compiling the Application
./<build_dir>/examples/dpdk-ipsec-secgw -c 0x3 -- -P -p 0x3 -u 0x1 \

- --event-schedule-type parallel \

where each option means:
* The ``--event-schedule-type`` option selects parallel ordering of event queues.
+* The ``--event-vector`` option enables event vectorization.
+
+* The ``--vector-size`` option specifies max vector size.
+
+* The ``--vector-tmo`` option specifies max timeout in nanoseconds for vectorization.
