Okay.

I'll describe the patch in more details, and it will help to review the code
I think.

Yes, this PMD actually supports more. But for now, it is limited by the
virtio-crypto vhost-crypto backend which only supports AES-CBC and SHA1,
so only AES-CBC and SHA1 can be tested, others are not guaranteed.
I think it's better to remove other cases and algorithms, we can add them
once the virtio-crypto vhost-user backend supports them.
What do you think?

Will do.
