The following call sequence is applicable when the IPSEC layer triggers

+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
