[PATCH v5] test: add cryptodev crosscheck suite

> 
> Add a validation test suite that helps in verifying that the output

> parameter combinations.
> 
> Crypto autotest performs a comprehensive testing of the cryptodev but since
> it performs verification by comparing against known vectors, the extend to
> which various parameters (like packet size) can be tested is limited. This
> test suite attempts to simulate various cases by running same test case on
> different cryptodevs and compares the output generated. The test suite
> relies on capabilities to determine the combinations of tests to be
> attempted.
> 
> A typical use case would be to compare outputs generated from a standard
> driver such as openSSL PMD and a new cryptodev PMD. This test suite is to
> compliment the testing coverage that crypto autotest provides.
> 
> Currently supported symmetric xforms(cipher, auth, aead) without chaining.

> 	-a <cryptodev> --vdev "crypto_openssl"

Hi Ciara,

Can you check if this version works for you and ack if all good?
