* \{
*
* For each of AES-128/192/256, four functions are defined:
*
* * a key schedule "expansion" function to prepare for encryption,
* * a 128-bit block encryption function using the key schedule,
* * a key schedule "reversion" function to prepare for decryption,
* * a 128-bit block decryption function using the "inverted" key schedule.
*
* The functions, respectively, are:
*
* * `aesni_raw_expand_key_scheduleNNN`,
* * `aesni_raw_encrypt_blockNNN`,
* * `aesni_raw_invert_key_scheduleNNN`,
* * `aesni_raw_decrypt_blockNNN`,
*
* where `NNN` is key length (either `128`, `192` or `256`).
