/**
 * hmac_sha384_kdf - HMAC-SHA384 based KDF (RFC 5295)
 * @secret: Key for KDF
 * @secret_len: Length of the key in bytes
 * @label: A unique label for each purpose of the KDF or %NULL to select
 *	RFC 5869 HKDF-Expand() with arbitrary seed (= info)
 * @seed: Seed value to bind into the key
 * @seed_len: Length of the seed
 * @out: Buffer for the generated pseudo-random key
 * @outlen: Number of bytes of key to generate
 * Returns: 0 on success, -1 on failure.
 *
 * This function is used to derive new, cryptographically separate keys from a
 * given key in ERP. This KDF is defined in RFC 5295, Chapter 3.1.2. When used
 * with label = NULL and seed = info, this matches HKDF-Expand() defined in
 * RFC 5869, Chapter 2.3.
