Subject: [PATCH v5 08/12] cryptodev: add asym op flags
Date: Wed,  1 Jun 2022 10:02:45 +0100	[thread overview]
Message-ID: <20220601090249.86865-9-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <20220601090249.86865-1-arkadiuszx.kusztal@intel.com>

- Added flags to rte_crypto_asym_op struct.
It may be shared between different algorithms.
- Added Diffie-Hellman padding flags.
Diffie-Hellman padding is used in certain protocols,
in others, leading zero bytes need to be stripped.
Even same protocol may use a different approach - most
glaring example is TLS1.2 - TLS1.3.
For ease of use, and to avoid additional copy
on certain occasions, driver should be able to return both.
