- 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.
