[dpdk-dev] [PATCH] cryptodev: rename experimental private data APIs

Fri Jul 6 15:39:42 CEST 2018
The name private_data is confusing in these APIs:
rte_cryptodev_sym_session_set_private_data()
rte_cryptodev_sym_session_get_private_data()
It refers to data added at the end of the session hdr for
use by the application.
The session already contains sess_private_data[index]
which is used to store private pmd data and most references to private
data refer to that.
e.g. external apis
rte_cryptodev_sym_get_private_session_size() and internal
set/get_session_private_data() refer to sess_private_data[].
So rename to user_data, i.e.
rte_cryptodev_sym_session_set_user_data()
rte_cryptodev_sym_session_get_user_data()
Refers to changes introduced here:
