[EXT] [PATCH v2 08/14] cryptodev: add public key verify option

[Akhil Goyal]

> - Added key exchange public key verify option.
> For some elliptic curves public point in DH exchange
> needs to be checked, if it lays on the curve.
> Modular exponentiation needs certain checks as well, though
> mathematically much easier.
> This commit adds verify option to asym_op operations.

If this is not for DH and only for ECDH, then specify this in comments also.
But IMO, it will be OK to use RTE_CRYPTO_ASYM_KE_PUB_KEY_VERIFY.
If it is not valid to use it for DH, we can mention in comments.
