> Subject: [PATCH v3 3/5] crypto/ipsec_mb: add remaining SGL support
> 
> The intel-ipsec-mb library supports SGL for GCM and ChaChaPoly
> algorithms using the JOB API.
> This support was added to AESNI_MB PMD previously, but the SGL feature
> flags could not be added due to no SGL support for other algorithms.
> 
> This patch adds a workaround SGL approach for other algorithms
> using the JOB API. The segmented input buffers are copied into a
> linear buffer, which is passed as a single job to intel-ipsec-mb.
> The job is processed, and on return, the linear buffer is split into the
> original destination segments.
> 
> Existing AESNI_MB testcases are passing with these feature flags added.
