This provides an OpenCrypto driver for Intel QuickAssist devices. The driver was initially ported from NetBSD and comes with a few improvements: - support for GMAC/AES-GCM, AES-CTR and AES-XTS, and support for SHA/HMAC-authenticated encryption - support for detaching the driver - various bug fixes - DH895X support Discussed with: jhb MFC after: 3 days Sponsored by: Rubicon Communications, LLC (Netgate) Differential Revision: https://reviews.freebsd.org/D26963
