Add new internal wrapper function for use by pci drivers as a
.probe function to attach to an event interface. Same as
rte_event_pmd_pci_probe, except the caller can specify the name.
Updated rte_event_pmd_pci_probe so as to not duplicate
code.

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.

When probing event device in secondary process skip reinitializing
the device data structure as it is already done in primary process.
When removing event device in secondary process skip closing the
event device as it should be done by primary process.

Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:
grep -L '^#include <rte_config.h>' -- \
$(grep -Rl \
$(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
build/include/rte_config.h) \
-- build/include/)
We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.
This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:
[...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
this scope
#define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
^
It also results in less visible issues, for instance rte_hash_crc.h relying
on RTE_ARCH_X86_64's presence to provide dedicated inline functions.
This patch partially reverts the commit below and adds missing include
lines to the remaining files.

The PCI lib defines the types and methods allowing to use PCI elements.
The PCI bus implements a bus driver for PCI devices by constructing
rte_bus elements using the PCI lib.
Move the relevant code out of the EAL to its expected place.
Libraries, drivers, unit tests and applications are updated to use the
new rte_bus_pci.h header when necessary.

The PCI helper file depends on some EAL definitions.
Spotted with devtools/check-includes.sh:
error: implicit declaration of function ‘rte_eal_process_type’
error: ‘RTE_PROC_PRIMARY’ undeclared
error: implicit declaration of function ‘rte_socket_id’
There was also this error because the inline keyword was missing:
error: ‘rte_event_pmd_pci_probe’ defined but not used
