I think this comment need to be re-written something like
/* Flag to denote public key will be returned without leading zero bytes
* and if the flag is not set, public key will be padded to the left with zeros(default) */
> +#define RTE_CRYPTO_ASYM_FLAG_SHARED_KEY_NO_PADDING RTE_BIT32(1)

Similar comment for this one also.
