[Fiona] max_nb_sessions must be also removed from
struct rte_cryptodev_pmd_init_params
Regards deprecation of max_nb_sessions from both structs:
Acked-by: Fiona Trahe <fiona.trahe at intel.com>
If removing the max_nb_sessions_per_qp, then the following functions should also be deprecated.
rte_cryptodev_queue_pair_attach_sym_session
rte_cryptodev_queue_pair_detach_sym_session
These and the max_nb_session_per_qp were added here at request of NXP:
