[dpdk-dev] [PATCH v9 4/5] cryptodev: change burst API to be crypto op oriented

Fiona Trahe fiona.trahe at intel.com
Thu Mar 10 16:41:12 CET 2016


From: Declan Doherty <declan.doherty at intel.com>

This patch modifies the crypto burst enqueue/dequeue APIs to operate on bursts
rte_crypto_op's rather than the current implementation which operates on
rte_mbuf bursts, this simplifies the burst processing in the crypto PMDs and the
use of crypto operations in general, including new functions for managing
rte_crypto_op pools.

These changes continues the separation of the symmetric operation parameters
from the more general operation parameters, which will simplify the integration
of asymmetric crypto operations in the future.

PMDs, unit tests and sample applications are also modified to work with the
modified and new API.
