e1fc5b7690 cryptodev: remove max number of sessions parameter
Most crypto PMDs do not have a limitation
of the number of the sessions that can be handled
internally. The value that was set before was not
actually used at all, since the sessions are created
at the application level.
Therefore, this value is not parsed from the initial
crypto parameters anymore and it is set to 0,
meaning that there is no actual limit.

a106fcce2c cryptodev: rename functions to get session size
rte_cryptodev_get_header_session_size() and
rte_cryptodev_get_private_session_size() functions are
targeting symmetric sessions.

With the future addition of asymmetric operations,
these functions need to be renamed from *cryptodev_*_session_*
to *cryptodev_sym_*_session_* to be symmetric specific.

The two original functions are marked as deprecated
and will be removed in 18.08, so applications can still
use the functions in 18.05.

17c36a6746 crypto/zuc: batch ops with same transform
The ZUC API to encrypt packets does not require the operations
to share the same key. Currently, the operations were being
batched only when they shared the same key, but this is not needed.

Instead, now operations will be batched based on the transform
(cipher only, auth only...).

f737f5cee6 cryptodev: change argument of driver registration
Pass an rte_driver to the RTE_PMD_REGISTER_CRYPTO_DRIVER macro
rather than an unspecified container which holds an rte_driver.
All the macro actually needs is the rte_driver, not the
container holding it.
This paves the way for a later patch in which a driver
will be registered which does not naturally derive from a
container and so avoids having to create an arbitrary container
to pass in the rte_driver.

This patch changes the cryptodev lib macro and all the
PMDs which use it.

0ff255e6fd crypto/zuc: do not append digest
When performing an authentication verification,
the PMD was using memory at the end of the input buffer,
to store temporarily the digest.
This operation requires the buffer to have enough
tailroom unnecessarily.
Instead, memory is allocated for each queue pair, to store
temporarily the digest generated by the driver, so it can
be compared with the one provided in the crypto operation,
without needing to touch the input buffer.

b3bbd9e5f2 cryptodev: support device independent sessions
Change crypto device's session management to make it
device independent and simplify architecture when session
is intended to be used on more than one device.

Sessions private data is agnostic to underlying device
by adding an indirection in the sessions private data
using the crypto driver identifier.
A single session can contain indirections to multiple device types.

New function rte_cryptodev_sym_session_init has been created,
to initialize the driver private session data per driver to be
used on a same session, and rte_cryptodev_sym_session_clear
to clear this data before calling rte_cryptodev_sym_session_free.

d803b4439d cryptodev: add user defined name for vdev
This patch adds a user defined name initializing parameter to cryptodev
library.

Originally, for software cryptodev PMD, the vdev name parameter is
treated as the driver identifier, and will create an unique name for each
device automatically, which is not necessarily as same as the vdev
parameter.

This patch allows the user to either create a unique name for his software
cryptodev, or by default, let the system creates a unique one. This should
help the user managing the created cryptodevs easily.

Examples:
CLI command fragment 1: --vdev "crypto_aesni_gcm_pmd"
The above command will result in creating a AESNI-GCM PMD with name of
"crypto_aesni_gcm_X", where postfix X is the number assigned by the system,
starting from 0. This fragment can be placed in the same CLI command
multiple times, resulting the postfixs incremented by one for each new
device.

CLI command fragment 2: --vdev "crypto_aesni_gcm_pmd,name=gcm1"
The above command will result in creating a AESNI-GCM PMD with name of
"gcm1". This fragment can be placed in the same CLI command multiple
times, as long as each having a unique name value.
