By reducing the iterations for the final stage of the self-test, the SW
eventdev tests can be fast enough for consideration in the fast-tests
suite. This enables them to be run as part of the regular patch CI
tests, and therefore increases the chances of catching any errors in
patches that may affect this component.

event/sw: add self test for ordered history list

This commit adds a unit test for an issue identified
where ordered history-list entries are not correctly
cleared when the returned event is of op RELEASE type.

The result of the history-list bug is that a future event
which re-uses that history-list slot, but has an op type
of FORWARD will incorrectly be reordered.

The existing unit-tests did not cover the RELEASE of an
ORDERED queue, and then stress-test the history-list by
iterating HIST_LIST times afterwards.

ERROR - XStats ID Reset test FAILED.
SW Eventdev Selftest Failed.
Test Failed

The flow ID is not set in the event, which results in an undefined
flow, whose value depends on what was previously in stack. Having
different flows for the packets makes the test to fail, since only one
flow is expected.

This only happens in -O3, where the same stack area is shared by the
event object and the address of the mbuf allocated in rte_gen_arp().

Fix this by properly initializing the flow id.

event/sw: add xstats to expose progress details

Today it is difficult to know if the SW Eventdev PMD is making
forward progress when it runs an iteration of its service. This
commit adds two xstats to give better visibility to the application.

The new xstats provide an application with which Eventdev ports
received work in the last iteration of scheduling, as well if
forward progress was made by the scheduler.

This patch implements an xstat for the SW PMD that exposes a
bitmask of ports that were scheduled to. In the unlikely case
that the SW PMD instance has 64 or more ports, return UINT64_MAX.

eventdev: express DLB/DLB2 PMD constraints

This commit implements the eventdev ABI changes required by
the DLB/DLB2 PMDs. Several data structures and constants are modified
or added in this patch, thereby requiring modifications to the
dependent apps and examples.

The DLB/DLB2 hardware does not conform exactly to the eventdev interface.
1) It has a limit on the number of queues that may be linked to a port.
2) Some ports a further restricted to a maximum of 1 linked queue.
3) DLB does not have the ability to carry the flow_id as part
of the event (QE) payload. Note that the DLB2 hardware is capable of
carrying the flow_id.

Following is a detailed description of the changes that have been made.

1) Add new fields to the rte_event_dev_info struct. These fields allow
the device to advertise its capabilities so that applications can take
the appropriate actions based on those capabilities.

struct rte_event_dev_info {
uint32_t max_event_port_links;
/**< Maximum number of queues that can be linked to a single event
* port by this device.
*/

uint8_t max_single_link_event_port_queue_pairs;
/**< Maximum number of event ports and queues that are optimized for
* (and only capable of) single-link configurations supported by this
* device. These ports and queues are not accounted for in
* max_event_ports or max_event_queues.
*/
}

2) Add a new field to the rte_event_dev_config struct. This field allows
the application to specify how many of its ports are limited to a single
link, or will be used in single link mode.

/** Event device configuration structure */
struct rte_event_dev_config {
uint8_t nb_single_link_event_port_queues;
/**< Number of event ports and queues that will be singly-linked to
* each other. These are a subset of the overall event ports and
* queues; this value cannot exceed *nb_event_ports* or
* *nb_event_queues*. If the device has ports and queues that are
* optimized for single-link usage, this field is a hint for how many
* to allocate; otherwise, regular event ports and queues can be used.
*/
}

3) Replace the dedicated implicit_release_disabled field with a bit field
of explicit port capabilities. The implicit_release_disable functionality
is assigned to one bit, and a port-is-single-link-only attribute is
assigned to other, with the remaining bits available for future assignment.

* Event port configuration bitmap flags */
#define RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL (1ULL << 0)
/**< Configure the port not to release outstanding events in
* rte_event_dev_dequeue_burst(). If set, all events received through
* the port must be explicitly released with RTE_EVENT_OP_RELEASE or
* RTE_EVENT_OP_FORWARD. Must be unset if the device is not
* RTE_EVENT_DEV_CAP_IMPLICIT_RELEASE_DISABLE capable.
*/
#define RTE_EVENT_PORT_CFG_SINGLE_LINK (1ULL << 1)

/**< This event port links only to a single event queue.
*
* @see rte_event_port_setup(), rte_event_port_link()
*/

#define RTE_EVENT_PORT_ATTR_IMPLICIT_RELEASE_DISABLE 3
/**
* The implicit release disable attribute of the port
*/

struct rte_event_port_conf {
uint32_t event_port_cfg;
/**< Port cfg flags(EVENT_PORT_CFG_) */
}

This patch also removes the depreciation notice and announce
the new eventdev ABI changes in release note.

event/sw: fix enqueue checks in self-test

This patch fixes a number of instances of the same return
value mis-check, where previously we checked for a negative
return value as error, however the API returns an unsigned
integer, so these return value checks are invalid.

The rte_event_enqueue_burst() API returns the number of
events enqueued, so in order to identify the error case,
we must check for != the number of intended enqueues.
