Adding support for IPsec events in rte_eth_event framework. In inline
IPsec offload, the per packet protocol defined variables, like ESN,
would be managed by PMD. In such cases, PMD would need IPsec events
to notify application about various conditions like, ESN overflow.

When introducing rte_eth_tx_prepare(), the constraints on checksum
pre-filling for Tx offloads were relaxed because implemented in
the PMDs with rte_net_intel_cksum_flags_prepare() helper.
As a consequence, these old requirements are removed for:
- PKT_TX_OUTER_IP_CKSUM
- PKT_TX_IP_CKSUM
- PKT_TX_[L4]_CKSUM
- PKT_TX_TCP_SEG
Not sure SCTP offload is properly implemented though.
A reference to rte_eth_tx_prepare() is added in rte_eth_tx_burst() doc.

Some DPDK applications wrongly assume these requirements:
- no hotplug, i.e. ports are never detached
- all allocated ports are available to the application
Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.
In order to fix this common mistake in all external applications,
the function rte_eth_dev_count is deprecated, while introducing
the new functions rte_eth_dev_count_avail and rte_eth_dev_count_total.

When application works with LSC interrupts the ethdev layer skips
the PMD callback and update according to the link status exists on
device data. It is because it assumes the link status on the device data
is the correct one since any link change is processed by the application.
As multiple PMDs install the link status interrupt handler only on port
start and uninstall it on port stop, the link status may be incorrect in
case the query is called after port stop or before port start.

The struct rte_eth_dev_data is used in ethdev fastpath routines
and it not aligned to cache line size. This patch fixes the ethdev
data alignment.
The alignment was broken from the "first public release" changeset
where ethdev data address was aligned only to the first port.
Remaining ports alignment was defined by the size of the struct
(rte_eth_dev_data). This scheme is not guaranteed to be cache line
aligned all the time.
"ethdev: add port ownership" change set introduced a
rte_eth_dev_shared_data container for port ownership change,
This resulted in rte_eth_dev->data memory for the first port also
as cache unaligned.
Added a compiler alignment attribute to make sure
rte_eth_dev->data always cache aligned so that CPU/compiler
1) Avoid sharing the element with another cache line
2) Can load/store the elements in struct rte_eth_dev_data as
naturally aligned.

at "ethdev: add port ownership" change set with

When querying either the name or the value of a stat using the xstats
APIs, a check is done to see if the regular stats API or the xstats APIs
for the driver need to be used. However, the id of the stat requested is
checked to see if it is greater than the number of basic stats, rather
than checking for greater-or-equal, meaning that the xstat with the lowest
id gets incorrectly treated as a basic stat.
This problem manifests itself when you call proc_info using "--xstats-id"

Ethernet port allocation was not thread safe, means 2 threads which tried

Actually, all the port configurations were not thread safe from ethdev
point of view.
The port ownership mechanism added to the ethdev is a good point to
redefine the synchronization rules in ethdev:
1. The port allocation and port release synchronization will be
managed by ethdev.
2. The port usage synchronization will be managed by the port owner.
3. The port ownership synchronization will be managed by ethdev.

The ownership of a port is implicit in DPDK.
Making it explicit is better from the next reasons:
1. It will define well who is in charge of the port usage synchronization.
2. A library could work on top of a port.
3. A port can work on top of another port.
Also in the fail-safe case, an issue has been met in testpmd.
We need to check that the application is not trying to use a port which
is already managed by fail-safe.
A port owner is built from owner id(number) and owner name(string) while
the owner id must be unique to distinguish between two identical entity
instances and the owner name can be any name.
The name helps to logically recognize the owner by different DPDK
entities and allows easy debug.
Each DPDK entity can allocate an owner unique identifier and can use it
and its preferred name to owns valid ethdev ports.
Each DPDK entity can get any port owner status to decide if it can
manage the port or not.
The mechanism is synchronized for both the primary process threads and
the secondary processes threads to allow secondary process entity to be
a port owner.
Add a synchronized ownership mechanism to DPDK Ethernet devices to
avoid multiple management of a device by different DPDK entities.
The current ethdev internal port management is not affected by this
feature.

There is no point to allow changing this user parameter by a caller.

The history is that the user parameter was initially used
by the callback implementation to pass some information
between the application and the driver:

Then a new parameter has been added to leave the user parameter
