186b14d685 cryptodev: make xform key pointer constant
This patch changes the key pointer data types in cipher, auth,
and aead xforms from "uint8_t *" to "const uint8_t *" for a
more intuitive and safe sessionn creation.

b063e843fa crypto/virtio: fix IV physical address
The physical address of IV required by Virtio was computed using
crypto operations' physical address plus the offset. However not
all crypto ops will have physical address field initialized and
compute it runtimely is costly. This patch fixes this problem by
adding iv field in virtio_crypto_op_cookie and does a memcpy of
iv instead.

82adb12a1f crypto/virtio: support burst enqueue/dequeue
This patch implements the functions of virtio_crypto_pkt_tx_burst()
and virtio_crypto_pkt_rx_burst(). The encryption and decryption requests
are placed in the data queue and are ultimately handled by
the backend crypto accelerators.

b7fa78c7d3 crypto/virtio: support session related ops
This patch implements session related operations, which includes creating
and destroying the session. For now, it only supports the session-oriented
API implementation. The control queue used to create or destroy sessions
for symmetric algorithms.

6f0175ff53 crypto/virtio: support basic PMD ops
This patch implements the basic operations of virtio crypto PMD, which
includes start, stop, close, information getting, queue setup and
release of the device.
The virtio crypto device has two types of queues, data queue and
control queue. It has one data queue at least and has one and only one
control queue. For example, if a virtio crypto device has N queues,
then [0, N-2] is the data queue index, N-1 is the control
queue index.

25500d4b80 crypto/virtio: support device init
This patch implements the initialization of the virtio crypto device.
The virtio crypto device conforms to virtio-1.0, so this patch only
supports modern mode operation.
The cryptodev is created at the virtio crypto pci device probing stage.
The function of virtio_crypto_pkt_tx_burst() is used to burst transfer
packets and virtio_crypto_pkt_rx_burst() is used to burst receive packets.

8769079ae0 crypto/virtio: add virtio crypto PMD
The virtio crypto device is a virtual cryptography device
as well as a kind of virtual hardware accelerator for
virtual machines. The linux kernel virtio-crypto driver
has been merged, and this patch introduces virtio crypto
PMD to achieve better performance.
