When rte_lpm.h is used on x86, -O0 option (no optimization at all)
given to gcc causes a compile error like this:
error: the last argument must be an 8-bit immediate
i24 = _mm_srli_si128(i24, sizeof(uint64_t));
-O0 option is useful for debugging and code coverage measurement, but
this error prevents DPDK programs from building. This patch replaces
"sizeof(uint64_t)" with a constant literal "8" to work around the issue.
The issue occurs on gcc/g++ versions from 4.8 to 5.

The DPDK documentation guidelines state that lines should be wrapped as
follows:
* The recommended style for the DPDK documentation is to put sentences on
separate lines. This allows for easier reviewing of patches. ...
* Long sentences should be wrapped at 120 characters +/- 10 characters.
They should be wrapped at words.
http://dpdk.org/doc/guides/contributing/documentation.html#line-length
However, in practice, users almost never submit doc patches in this format.
Instead most users wrap their doc patches at 80 characters.
This patch updates the documentation contributors guide to reflect this
as the recommended guideline.

API changes are planned for 17.08 to made sessions agnostic to the
underlaying devices, removing coupling with crypto PMDs, so a single
session can be used on multiple devices.
It requires to change "struct rte_cryptodev_sym_session" to store more
than one private data for devices, as well as remove redundant dev_id
and dev_type.
Effected public functions:
- rte_cryptodev_sym_session_pool_create
- rte_cryptodev_sym_session_create
- rte_cryptodev_sym_session_free
While session will not be directly associated with device, followed API
will be changed adding uint8_t dev_id to the argument list:
- rte_cryptodev_queue_pair_attach_sym_session
- rte_cryptodev_queue_pair_detach_sym_session

Refer to RFC patch - cryptodev: remove crypto device type enumeration
It is planned to remove device type enumeration rte_cryptodev_type from
library to remove the coupling between crypto PMD and the librte_cryptodev.
In this case following stuctures will be changed: rte_cryptodev_session,
rte_cryptodev_sym_session, rte_cryptodev_info, rte_cryptodev.
It is planned to change the function rte_cryptodev_count_devtype().
The function prototype doesn’t clearly show the operation.
>From next release 17.08 the dev_type will be changed to driver_id.
So the function name will change to rte_cryptodev_device_count_by_driver().

This is an ABI change notice for DPDK 17.08 in ethdev
about changes in rte_eth_txmode structure.
Currently Tx offloads are enabled by default, and can be disabled
using ETH_TXQ_FLAGS_NO* flags. This behaviour is not consistent with
the Rx side where the Rx offloads are disabled by default and enabled
according to bit field in rte_eth_rxmode structure.
The proposal is to disable the Tx offloads by default, and provide
a way for the application to enable them in rte_eth_txmode structure.
Besides of making the Tx configuration API more consistent for
applications, PMDs will be able to provide a better out of the
box performance.
Finally, as part of the work, the ETH_TXQ_FLAGS_NO* will
be superseded as well.

The PCI and virtual bus are planned to be moved to the generic
drivers/bus directory in v17.08. For this change to be possible, the EAL
must be made completely independent.
The rte_devargs structure currently holds device representation internal
to those two busses. It must be made generic before this work can be
completed.
Instead of using either a driver name for a vdev or a PCI address for a
PCI device, a devargs structure will have to be able to describe any
possible device on all busses, without introducing dependencies on
any bus-specific device representation. This will break the ABI for this
structure.
Additionally, an evolution will occur regarding the device parsing
from the command-line. A user must be able to set which bus will handle
which device, and this setting is integral to the definition of a
device.
The format has not yet been formally defined, but a proposition will
follow soon for a new command line parameter format for all devices.
