Subject: [PATCH v5 3/5] crypto: hide asym session structure
Date: Thu, 10 Feb 2022 14:01:51 +0000	[thread overview]
Message-ID: <20220210140153.3439676-4-ciara.power@intel.com> (raw)
In-Reply-To: <20220210140153.3439676-1-ciara.power@intel.com>

The rte_cryptodev_asym_session structure is now moved to an internal
header. This will no longer be used directly by apps,
private session data can be accessed via get API.

Signed-off-by: Ciara Power <ciara.power@intel.com>
Acked-by: Fan Zhang <roy.fan.zhang@intel.com>

v4:
  - Initialised session variables as NULL.
  - Removed docs code additions, these are included due to patch 1
    changing sample doc to use literal includes.
v3:
  - Removed the incorrect use of void * for asym session in drivers,
    these are internal and can use the struct directly as before.
  - Fixed other internal functions and comments that were incorrectly
    changed to use void *sess.
  - Added documentation.
