Then all apps will always *have to* setup  sync parameters in xform.
What you suggest is *mandatory* sync mode: user always has to setup sync
mode params if PMD does support it (no matter does he plan to use sync mode or not).   
Which means behavior change in existing apps.

I think warning is not enough.
There should be a clear way (API) for developer to realize is the created session
can be used by sync API data-path or not.

What I am saying: if let-say lookaside-proto/inline-crypto/inline-proto
deserves its own case in rte_security/rte_crypto API,
I don't understand why cpu-crypto doesn't.

> Those 4 are controlled using 2 set of APIs.

Yes there are 2 API sets (rte_cryptodev/rte_security),
but in fact if you look at ipsec-secgw and librte_ipsec we have 4 different code paths.
For both create_session() and ipsec_enqueue() we have a big switch() with 4 different cases.
Nearly the same for librte_ipsec - we have different prepare/process
function pointers for each security type.

If I would see a clean approach to implement desired functionality
without introducing new API - I would definitely support it.
The problem is  that from my perspective,
what you suggesting with existing API will bring more drawbacks then positives.
BTW, our first approach (via rte_security) does reuse existing API,
so if adding new API is the main concern - let's reconsider that path.
