 The following call sequence is applicable when the IPSEC layer triggers
 an encryption operation with the esp_output function. During

+configuration, the administrator set up the use of seqiv(rfc4106(gcm(aes)))
+as the cipher for ESP. The following call sequence is now depicted in
+the ASCII art above:
 
 1. esp_output() invokes crypto_aead_encrypt() to trigger an
    encryption operation of the AEAD cipher with IV generator.
 
-   In case of GCM, the SEQIV implementation is registered as GIVCIPHER
-   in crypto_rfc4106_alloc().
-
-   The SEQIV performs its operation to generate an IV where the core
-   function is seqiv_geniv().
+   The SEQIV generates the IV.
 
 2. Now, SEQIV uses the AEAD API function calls to invoke the associated
    AEAD cipher. In our case, during the instantiation of SEQIV, the
