[v2,1/7] cryptodev: add APIs to get/set event metadata
Checks
Commit Message
From: Volodymyr Fialko <vfialko@marvell.com>
Currently, crypto session userdata is used to set event crypto
metadata from the application and the driver is dereferencing it
in driver which is not correct. User data is meant to be opaque
to the driver.
To support this, new API is added to get and set event crypto
metadata. The new API, rte_cryptodev_set_session_event_mdata,
allows setting event metadata in session private data which is
filled inside PMD using a new cryptodev op. This operation
can be performed on any of the PMD supported sessions
(sym/asym/security).
For SW abstraction of event crypto adapter to be used by
eventdev library, a new field is added in asymmetric crypto
session for now and for symmetric case, current implementation
of using userdata is used. Symmetric cases cannot be fixed now,
as it will be ABI breakage which will be resolved in DPDK 22.11.
