[dpdk-dev] [PATCH v2 2/3] doc: announce deprecation for attach/detach crypto session

[Pablo de Lara]

Functions rte_cryptodev_queue_pair_attach_sym_session
and rte_cryptodev_queue_pair_detach_sym_sessions
are not really used in any of the crypto drivers
(only one driver implements it and it just return 0).
Therefore, this API can be deprecated from 18.02
and removed in 18.05.
