The crypto dev wont be able to make difference whether to alter it (for any other usecase) or not(for event case). As per definition of impl_opaque is meant to be consumed by driver. Hence this will contradict the usage. Since impl_opaque in rte_crypto_op is exposed to driver. Drivers are free to use it. You may consider using mbuf dynamic fields for setting some userdata for your use case for each packet. See rte_security_dynfield and add a fastpath cryptodev API to set pkt userdata which is opaque to driver (similar to rte_security_set_pkt_metadata). Or else add a similar schema to introduce dynamic fields in rte_crypto_op. Regards, Akhil
