[Shally] this overall look repetitive here. Since now this buffer is both input and output depending on op_type.
How about , if we just change description to: 
Pointer to plaintext buffer. This buffer is input to RSA_CRYPTO_ASYM_OP_TYPE_ENCRYPT/ SIGN, VERIFY
And Output to RTE_CRYPTO_ASYM_OP_TYPE_DECRYPT

[Shally] So is my suggestion here. Change to like "Pointer to Ciphetext buffer ..."
