[Anoob] The above line could be confusing. I guess you will need a comma after "crypto does".

It works the same way as symmetric crypto does, namely xform is used directly by the crypto op.

[Even "does" may not be required]

Updated release notes as
+* **Added cryptodev asymmetric session-less operation.**
+
+  Added session-less option to cryptodev asymmetric structure. It works the same
+  way as symmetric crypto, corresponding xform is used directly by the crypto op.
