2    Please note that the kernel crypto API contains the AEAD givcrypt
3    API (crypto_aead_giv* and aead_givcrypt_* function calls in
4    include/crypto/aead.h). This API is obsolete and will be removed
5    in the future. To obtain the functionality of an AEAD cipher with
6    internal IV generation, use the IV generator as a regular cipher.
7    For example, rfc4106(gcm(aes)) is the AEAD cipher with external
8    IV generation and seqniv(rfc4106(gcm(aes))) implies that the kernel
9    crypto API generates the IV. Different IV generators are available.
