ad976bd40d ethdev: add extensions attributes to IPv6 item
Using the current implementation of DPDK, an application cannot match on
IPv6 packets, based on the existing extension headers, in a simple way.

Field 'Next Header' in IPv6 header indicates type of the first extension
header only. Following extension headers can't be identified by
inspecting the IPv6 header.
As a result, the existence or absence of specific extension headers
can't be used for packet matching.

For example, fragmented IPv6 packets contain a dedicated extension header
(which is implemented in a later patch of this series).
Non-fragmented packets don't contain the fragment extension header.
For an application to match on non-fragmented IPv6 packets, the current
implementation doesn't provide a suitable solution.
Matching on the Next Header field is not sufficient, since additional
extension headers might be present in the same packet.
To match on fragmented IPv6 packets, the same difficulty exists.

This patch implements the update as detailed in RFC [1].
A set of additional values will be added to IPv6 header struct.
These values will indicate the existence of every defined extension
header type, providing simple means for identification of existing
extensions in the packet header.
Continuing the above example, fragmented packets can be identified using
the specific value indicating existence of fragment extension header.
To match on non-fragmented IPv6 packets, need to use has_frag_ext 0.
To match on fragmented IPv6 packets, need to use has_frag_ext 1.
To match on any IPv6 packets, the has_frag_ext field should
not be specified for match.

4d9fd85fb5 ethdev: add shared actions to flow API
Introduce extension of flow action API enabling sharing of single
rte_flow_action in multiple flows. The API intended for PMDs, where
multiple HW offloaded flows can reuse the same HW essence/object
representing flow action and modification of such an essence/object
affects all the rules using it.

Motivation and example
===
Adding or removing one or more queues to RSS used by multiple flow rules
imposes per rule toll for current DPDK flow API; the scenario requires
for each flow sharing cloned RSS action:
- call `rte_flow_destroy()`
- call `rte_flow_create()` with modified RSS action

API for sharing action and its in-place update benefits:
- reduce the overhead of multiple RSS flow rules reconfiguration
- optimize resource utilization by sharing action across multiple
  flows

Change description
===

Shared action
===
In order to represent flow action shared by multiple flows new action
type RTE_FLOW_ACTION_TYPE_SHARED is introduced (see `enum
rte_flow_action_type`).
Actually the introduced API decouples action from any specific flow and
enables sharing of single action by its handle across multiple flows.

Shared action create/use/destroy
===
Shared action may be reused by some or none flow rules at any given
moment, i.e. shared action resides outside of the context of any flow.
Shared action represent HW resources/objects used for action offloading
implementation.
API for shared action create (see `rte_flow_shared_action_create()`):
- should allocate HW resources and make related initializations required
  for shared action implementation.
- make necessary preparations to maintain shared access to
  the action resources, configuration and state.
API for shared action destroy (see `rte_flow_shared_action_destroy()`)
should release HW resources and make related cleanups required for shared
action implementation.

In order to share some flow action reuse the handle of type
`struct rte_flow_shared_action` returned by
rte_flow_shared_action_create() as a `conf` field of
`struct rte_flow_action` (see "example" section).

If some shared action not used by any flow rule all resources allocated
by the shared action can be released by rte_flow_shared_action_destroy()
(see "example" section). The shared action handle passed as argument to
destroy API should not be used any further i.e. result of the usage is
undefined.

Shared action re-configuration
===
Shared action behavior defined by its configuration can be updated via
rte_flow_shared_action_update() (see "example" section). The shared
action update operation modifies HW related resources/objects allocated
on the action creation. The number of operations performed by the update
operation should not depend on the number of flows sharing the related
action. On return of shared action update API action behavior should be
according to updated configuration for all flows sharing the action.

Shared action query
===
Provide separate API to query shared action state (see
rte_flow_shared_action_update()). Taking a counter as an example: query
returns value aggregating all counter increments across all flow rules
sharing the counter. This API doesn't query shared action configuration
since it is controlled by rte_flow_shared_action_create() and
rte_flow_shared_action_update() APIs and no supposed to change by other
means.

example
===

struct rte_flow_action actions[2];
struct rte_flow_shared_action_conf conf;
struct rte_flow_action action;
/* skipped: initialize conf and action */
struct rte_flow_shared_action *handle =
	rte_flow_shared_action_create(port_id, &conf, &action, &error);
actions[0].type = RTE_FLOW_ACTION_TYPE_SHARED;
actions[0].conf = handle;
actions[1].type = RTE_FLOW_ACTION_TYPE_END;
/* skipped: init attr0 & pattern0 args */
struct rte_flow *flow0 = rte_flow_create(port_id, &attr0, pattern0,
					actions, error);
/* create more rules reusing shared action */
struct rte_flow *flow1 = rte_flow_create(port_id, &attr1, pattern1,
					actions, error);
/* skipped: for flows 2 till N */
struct rte_flow *flowN = rte_flow_create(port_id, &attrN, patternN,
					actions, error);
/* update shared action */
struct rte_flow_action updated_action;
/*
 * skipped: initialize updated_action according to desired action
 * configuration change
 */
rte_flow_shared_action_update(port_id, handle, &updated_action, error);
/*
 * from now on all flows 1 till N will act according to configuration of
 * updated_action
 */
/* skipped: destroy all flows 1 till N */
rte_flow_shared_action_destroy(port_id, handle, error);

805b8faa6b ethdev: introduce flow sample action
When using full offload, all traffic will be handled by the HW, and
forwarded to the requested VF or wire and the control application does
not see this traffic anymore. So there's a need for an action that
enables the control application some forwarded traffic visibility.

The solution introduces a new action that will sample the incoming
traffic and send a duplicated traffic with the specified ratio to the
application, while the original packet will continue to the target
destination.

The packets sampled equals is '1/ratio', the ratio value set to 1
means that the packets will be completely mirrored. The sample packet
can be assigned with different set of actions from the original packet.

In order to support the sample packet in rte_flow, new rte_flow action
definition RTE_FLOW_ACTION_TYPE_SAMPLE and structure rte_flow_action_sample
will be introduced.

1372d0cb2a ethdev: fix xstat name of basic stats per queue
As described in doc/guides/prog_guide/poll_mode_drv.rst,
the naming scheme for the xstats is parts separated with underscore:
	* direction
	* detail 1
	* detail 2
	* detail n
	* unit
where detail 1 can be "q" followed with a queue number.
It means the name of the stats per queue should be rx_qN_* or tx_qN_*.

The second underscore was missing so far.
Fixing the basic xstat names may be considered an API change,
that's why it should not be backported.

While fixing this mistake, some examples of the naming scheme
are given as part of the API documentation of rte_eth_xstat_name.

fa5054c4bb vhost: fix external mbuf creation
In virtio_dev_extbuf_alloc(), the shinfo structure used to store
the reference counter and the free callback of the external buffer
is by default stored inside the mbuf data.

This is wrong because the mbuf (and its data) can be freed before
the external buffer, for instance in the following situation:

  pkt2 = rte_pktmbuf_alloc(mp);
  rte_pktmbuf_attach(pkt2, pkt);
  rte_pktmbuf_free(pkt);

After this, pkt is freed, but it still contains shinfo, which is
referenced by pkt2.

Fix this by always storing the shinfo beside the external buffer.

e8a83681f4 eal/x86: fix memcpy AVX-512 enablement
When testing on some x86 platforms, code compiled with meson was observed
running at a different power-license level to that compiled with make. This
is due to the fact that meson auto-detects the instruction sets available
on the system and enabled AVX512 rte_memcpy when AVX512 was available,
while on make, a build time AVX-512 flag needed to be explicitly set to
enable that AVX512 rte_memcpy code path.

In the absence of runtime path selection for rte_memcpy - which is
complicated by it being a static inline function in a header file - we can
fix this behaviour regression by similarly having a build-time option which
must be set to enable the AVX-512 memcpy path.

75d113136f 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.

80d1a9aff7 ethdev: make flow API thread safe
Currently, the rte_flow functions are not defined as thread safe.
DPDK applications either call the functions in single thread or
protect any concurrent calling for the rte_flow operations using
a lock.

For PMDs support the flow operations thread safe natively, the
redundant protection in application hurts the performance of the
rte_flow operation functions.

And the restriction of thread safe is not guaranteed for the
rte_flow functions also limits the applications' expectation.

This feature is going to change the rte_flow functions to be thread
safe. As different PMDs have different flow operations, some may
support thread safe already and others may not. For PMDs don't
support flow thread safe operation, a new lock is defined in ethdev
in order to protects thread unsafe PMDs from rte_flow level.

A new RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE device flag is added to
determine whether the PMD supports thread safe flow operation or not.
For PMDs support thread safe flow operations, set the
RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE flag, rte_flow level functions will
skip the thread safe helper lock for these PMDs. Again the rte_flow
level thread safe lock only works when PMD operation functions are
not thread safe.

For the PMDs which don't want the default mutex lock, just set the
flag in the PMD, and add the prefer type of lock in the PMD. Then
the default mutex lock is easily replaced by the PMD level lock.

The change has no effect on the current DPDK applications. No change
is required for the current DPDK applications. For the standard posix
pthread_mutex, if no lock contention with the added rte_flow level
mutex, the mutex only does the atomic increasing in
pthread_mutex_lock() and decreasing in
pthread_mutex_unlock(). No futex() syscall will be involved.

486f067a41 security: modify PDCP xform to support SDAP
The SDAP is a protocol in the LTE stack on top of PDCP for
QOS. A particular PDCP session may or may not have
SDAP enabled. But if it is enabled, SDAP header should be
authenticated but not encrypted if both confidentiality and
integrity is enabled. Hence, the driver should be intimated
from the xform so that it skip the SDAP header while encryption.

A new field is added in the PDCP xform to specify SDAP is enabled.
The overall size of the xform is not changed, as hfn_ovrd is just
a flag and does not need uint32. Hence, it is converted to uint8_t
and a 16 bit reserved field is added for future.

057d9a92f0 eal: fix build with conflicting libc variable memory_order
The cited commit introduced functions with 'int memory_order' argument.
The C11 standard section 7.17.1.4 defines 'memory_order' as the
"enumerated type whose enumerators identify memory ordering constraints".

A compilation error occurs:
error: declaration of 'memory_order' shadows a global declaration
    [-Werror=shadow]
     rte_atomic_thread_fence(int memory_order)

This issue was hit when trying to compile OVS with gcc 4.8.5. This
compiler version does not provide stdatomic.h, so enum memory_order is
redefined in OVS code.
In another case, if the compiler does provide stdatomic.h header,
passing -Wsystem-headers in the CFLAGS will also cause that failure.

Fix it by changing the argument name 'memory_order' to 'memorder'.
