sha384_prf() function

sha384_prf - SHA384-based Key derivation function (IEEE 802.11ac, 11.6.1.7.2) @key: Key for KDF @key_len: Length of the key in bytes @label: A unique label for each purpose of the PRF @data: Extra data to bind into the key @data_len: Length of the data @buf: Buffer for the generated pseudo-random key @buf_len: 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.
