Hi Satya, What you are attempting is lookaside crypto offload. So in that case the mbuf->ol_flags fields won’t be used. Also, I’m not sure what all algos are available in ‘crypto_null’. In lookaside crypto offload model, packets are received in ipsec-secgw and lookup happens in ipsec-secgw. The packets would be then submitted to cryptodev for crypto processing. The cryptodev would be able to process the packet only if the algos specified are supported by it. IPsec processing also would be done in the application (ie, ipsec-secgw). Once all this done, it is submitted to ethdev for Tx. You can check the code and you will be able to figure out what I have described above.
Please do check ipsec-secgw documentation, if you haven’t done it already.
