crypto: add virtio-crypto driver
This patch introduces virtio-crypto driver for Linux Kernel. The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in the future. The virtio crypto device provides the following cryptoservices: CIPHER, MAC, HASH, and AEAD. For more information about virtio-crypto device, please see: http://qemu-project.org/Features/VirtioCrypto CC: Michael S.
