As per current design, rte_cryptodev_sym_session_create() and
rte_cryptodev_sym_session_init() use separate mempool objects
for a single session.
And structure rte_cryptodev_sym_session is not directly used
by the application, it may cause ABI breakage if the structure
is modified in future.
To address these two issues, the rte_cryptodev_sym_session_create
will take one mempool object that the session and session private
data are virtually/physically contiguous, and initializes both
fields. The API rte_cryptodev_sym_session_init is removed.
rte_cryptodev_sym_session_create will now return an opaque session
pointer which will be used by the app and other APIs.
In data path, opaque session pointer is attached to rte_crypto_op
and the PMD can call an internal library API to get the session
private data pointer based on the driver id.
Note: currently single session may be used by different device
drivers, given it is initialized by them. After the change the
session created by one device driver cannot be used or
reinitialized by another driver.

Previously, the pipeline build operation was done based on the
specification file (typically produced by the P4 compiler), then the C
code with optimized functions for the pipeline actions and
instructions was generated, built into a shared object library, loaded
and installed into the pipeline in a completely hardcoded and
non-customizable way.
Now, this process is split into three explicit stages:
i) code generation (specification file -> C file);
ii) code build (C file -> shared object library);
iii) code installation (library load into the pipeline).

The P4 language requires marking a header as valid before any of the
header fields are written as opposed to after the writes are done.
Hence, the optimization of replacing the sequence of instructions to

-> dma" to "validate + mov all -> dma".

Previously, on lookup hit, the hit key had its timer automatically
rearmed with the same timeout in order to prevent its expiration. Now,
a broader set of actions is available on lookup hit, which has to be
managed explicitly: the key can have its timer rearmed with the same
or with a different timeout, or the key timer can be left unmodified.
The latter option allows the key to expire naturally when the timer
eventually runs out, unless the key is hit again and its timer rearmed
at that point. Needed by the TCP connection tracking state machine.

Add support for packet recirculation. The current packet is flagged
for recirculation using the new "recirculate" instruction; on TX, this
flag causes the packet to execute the full pipeline again as if it was
a new packet, except the packet meta-data is preserved. The new
"recircid" instruction can be used to read the pass number in case the
packet goes several times through the pipeline.

The packet mirroring is configured through slots and sessions, with
the number of slots and sessions set at init.
The new "mirror" instruction assigns one of the existing sessions to a
specific slot, which results in scheduling a mirror operation for the

transmitted or dropped.
Several copies of the same input packet can be mirrored to different
output ports by using multiple slots.
