[PATCH v3] doc: announce rte_ipsec API changes

[Konstantin Ananyev]

> In case of event mode operations where event device can help in atomic
> sequence number increment across cores, sequence number need to be
> provided by the application instead of being updated in rte_ipsec or the
> PMD.
> 
> To support this, two new APIs rte_ipsec_pkt_crypto_sqn_assign and
> rte_ipsec_pkt_crypto_xprepare are introduced decoupling the seq no update
> functionality from the existing rte_ipsec_pkt_crypto_prepare API.
> Additionally, a new flag ``RTE_IPSEC_SAFLAG_SQN_ASSIGN_DISABLE`` will be
> added to allow disabling of internal sequence number update inside IPsec
> library.

> +  by application. To allow the same, two new APIs are being introduced:
> +  rte_ipsec_pkt_crypto_sqn_assign and rte_ipsec_pkt_crypto_xprepare. These APIs
> +  separate the seq no update functionality from the existing rte_ipsec_pkt_crypto_prepare
> +  API. Corresponding configure structure changes are being made for the new APIs.
> +  Additionally a new flag ``RTE_IPSEC_SAFLAG_SQN_ASSIGN_DISABLE`` is
> +  introduced to disable sequence number assignment in lib IPsec.
