[dpdk-dev] [PATCH v2] cryptodev: add ff_disable field in cryptodev config
Anoob Joseph

Tue Jun 25 07:39:24 CEST 2019
Adding a new field, ff_disable, to allow applications to control the
features enabled on the crypto device. This would allow for efficient
usage of HW/SW offloads.
Signed-off-by: Anoob Joseph <anoobj at marvell.com>
---
v2:
* Updated test & example applications to incorporate the default setting
for ff_disable field. Disabling SECURITY offload for cases where only
crypto is applicable & asymmetric crypto in case of ipsec etc.
