AEAD is a type of crypto algorithms, just like cipher or hash.

Authenc is a particular AEAD algorithm, just like AES is a cipher
or SHA is a hash.

Well IPsec uses the AEAD interface so it loads the aead.ko due
to symbol dependencies.  The authenc module is loaded if the
user specifies a normal block cipher and hash algorithm.
