[PATCH 0/4] crypto: Key Derivation Function (SP800-108)

Hi, this patch set implements all three key derivation functions defined in SP800-108. The implementation is provided as a template for random number generators, since a KDF can be considered a form of deterministic RNG where the key material is used as a seed. With the KDF implemented as a

GCM: cra_name == cra_driver_name

Hi Herbert, with the current cryptodev tree, when I call a compound AEAD cipher with cra_driver_name for the first time, this cra_driver_name gets registered also as cra_name. Note, using other compound ciphers (like HMAC or symmetric ciphers), I do not see that error. With that registering,
