67f64f2e12 mbuf_offload: remove library
As cryptodev library does not depend on mbuf_offload library
any longer, this patch removes it.

c0f87eb525 cryptodev: change burst API to be crypto op oriented
This patch modifies the crypto burst enqueue/dequeue APIs to operate on bursts
rte_crypto_op's rather than the current implementation which operates on
rte_mbuf bursts, this simplifies the burst processing in the crypto PMDs and the
use of crypto operations in general, including new functions for managing
rte_crypto_op pools.

These changes continues the separation of the symmetric operation parameters
from the more general operation parameters, which will simplify the integration
of asymmetric crypto operations in the future.

PMDs, unit tests and sample applications are also modified to work with the
modified and new API.

1bd407fac8 cryptodev: extract symmetric operations
This patch splits symmetric specific definitions and
functions away from the common crypto APIs to facilitate the future extension
and expansion of the cryptodev framework, in order to allow asymmetric
crypto operations to be introduced at a later date, as well as to clean the
logical structure of the public includes. The patch also introduces the _sym
prefix to symmetric specific structure and functions to improve clarity in
the API.

d5176d630d qat: fix build on 32-bit systems
Fixing build on 32-bit systems on quick assist driver - for example:
drivers/crypto/qat/qat_crypto.c: In function ‘qat_alg_write_mbuf_entry’:
drivers/crypto/qat/qat_crypto.c:408:34: error:
cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

693f715da4 remove extra parentheses in return statement
fix the error reported by checkpatch:
  "ERROR: return is not a function, parentheses are not required"

remove parentheses in return like:
  "return (logical expressions)"

remove parentheses in return a function like:
  "return (rte_mempool_lookup(...))"

Fixes: 6307b909b8e0 ("lib: remove extra parenthesis after return")

3e718b8169 mk: fix external shared library dependencies of drivers
Similar to commit 5f9115e58cc6f304ff4ade694cf5823d32887d1a, but
for qat and mpipe drivers. The former did not exist when the
previous patch was sent and latter I just missed.

1703e94ac5 qat: add driver for QuickAssist devices
This patch adds a PMD for the Intel Quick Assist Technology DH895xxC
hardware accelerator.

This patch depends on a QAT PF driver for device initialization. See
the file docs/guides/cryptodevs/qat.rst for configuration details

This patch supports a limited subset of QAT device functionality,
currently supporting chaining of cipher and hash operations for the
following algorithmsd:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)

Hash algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Some limitation on this patchset which shall be contributed in a
subsequent release:
 - Chained mbufs are not supported.
 - Hash only is not supported.
 - Cipher only is not supported.
 - Only in-place is currently supported (destination address is
   the same as source address).
 - Only supports session-oriented API implementation (session-less
   APIs are not supported).
