- Add two new module parameters to icp (icp_aes_impl, icp_gcm_impl) that control the crypto implementation. At the moment there is a choice between generic and aesni (on platforms that support it). - This enables support for AES-NI and PCLMULQDQ-NI on AMD Family 15h (bulldozer) and newer CPUs (zen). - Modify aes_key_t to track what implementation it was generated with as key schedules generated with various implementations are not necessarily interchangable.
