[Fiona] The code is ok but I think a little more is needed.
As all PMDs don't support sessionless, this needs to be handled as an optional capability.
And in future some PMDs may only support SESSIONLESS and some only support WITH_SESSION.
So I propose adding 2 feature flags to the API
and including in this patch the PMD and UT changes to set and test the first flag.
We'll follow up with SESSIONLESS QAT implementation and UTs in a separate patchset.
Also documentation updates should go with this API patch, i.e.
- update section 16.7.2 in the cryptodev programmers guide - and review that doc in case other sections need updating.
- fix comment in rte_crypto.h under STATUS_INVALID_SESSION
- release note
