-        * AEAD memory structure: For encryption, the tag is appended to the
-        * ciphertext which implies that the memory allocated for the ciphertext
-        * must be increased by the tag length. For decryption, the tag
-        * is expected to be concatenated to the ciphertext. The plaintext
-        * therefore has a memory size of the ciphertext minus the tag length.
-        *
-        * The memory structure for cipher operation has the following
-        * structure:
-        *      AEAD encryption input:  assoc data || plaintext
-        *      AEAD encryption output: cipherntext || auth tag
-        *      AEAD decryption input:  assoc data || ciphertext || auth tag
-        *      AEAD decryption output: plaintext
+        * Please see documentation of aead_request_set_crypt for the
+        * description of the AEAD memory structure expected from the caller.
