[Fiona] I think it's useful that it's under the digest-encrypted case notes.
So ok as is and is good to have info in both places people may look.
However if we want to avoid duplication, then I'd prefer to keep here and add a
note
under the specific params to direct to check here. Like:
* and
ZUC @ RTE_CRYPTO_CIPHER_ZUC_EEA3,
- * this field should be in bits.
+ * this field should be in bits. See
also
+ * notes about digest-encrypted case.
