app/regex: fix crash in options parsing
getopt_long() parses command-line arguments. One of its arguments
'longopts' is a pointer to the first element of an array of struct
option. The last element of the array has to be filled with zeros
to mark the end of options. For example:
struct option longopts[] = {
{ "help", 0, 0, ARG_HELP},
....
/* End of options */
{ 0, 0, 0, 0 }
};
This commit adds the last element. Prior to this commit getopt_long()
continued parsing beyond the longopts[] array which occasionally caused
segmentation faults.

build: standardize component names and defines
As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.
Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.
Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.
To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

this case following the "bus" directory, we can simplify somewhat the build

than having it's build distributed across 3 folders.
This also opens up the possibility of building the QAT driver with crypto
only and the compression part disabled. It further allows more sensible
naming of the resulting shared library in case of standardizing library

build: add defines for compatibility with make build
The defines used to indicate what crypto, compression and eventdev drivers
were being built were different to those used in the make build, with meson
defining them with "_PMD" at the end, while make defined them with "_PMD"
in the middle and the specific driver name at the end. This might cause
compatibility issues for applications which used the older defines, which
switching to build against new DPDK releases.
As well as changing the default to match that of make, meson also
special-cases the crypto/compression/event drivers to have both defines
provided. This ensures compatibility for these macros with both meson and
make from older versions.
For a selection of other libraries and drivers, there were other
incompatibilities between the meson and make-defined macros which were not
previously highlighted in a deprecation notice, so we add per-macro
compatibility defines for these to ease the transition from make to meson.

In all distributor tests there is a chance that tests
will send packets to distributor with rte_distributor_process()
before workers are started and requested for packets.
This patch ensures that all packets are delivered to workers

of successfully processed packets reaches required by test.
Change is applied to every first call in test case.

The sanity test with worker shutdown delegates all bufs

The test intention is to verify if packets assigned to

However the shutdown core was not always the one, that was
processing packets. The lcore processing mbufs might be different

distributor: handle worker shutdown in burst mode
The burst version of distributor implementation was missing proper
handling of worker shutdown. A worker processing packets received
from distributor can call rte_distributor_return_pkt() function
informing distributor that it want no more packets. Further calls to
rte_distributor_request_pkt() or rte_distributor_get_pkt() however
should inform distributor that new packets are requested again.
Lack of the proper implementation has caused that even after worker
informed about returning last packets, new packets were still sent
from distributor causing deadlocks as no one could get them on worker
side.
This patch adds handling shutdown of the worker in following way:
1) It fixes usage of RTE_DISTRIB_VALID_BUF handshake flag. This flag
was formerly unused in burst implementation and now it is used
for marking valid packets in retptr64 replacing invalid use
of RTE_DISTRIB_RETURN_BUF flag.
2) Uses RTE_DISTRIB_RETURN_BUF as a worker to distributor handshake
in retptr64 to indicate that worker has shutdown.
3) Worker that shuts down blocks also bufptr for itself with
RTE_DISTRIB_RETURN_BUF flag allowing distributor to retrieve any
in flight packets.
4) When distributor receives information about shutdown of a worker,
it: marks worker as not active; retrieves any in flight and backlog
packets and process them to different workers; unlocks bufptr64
by clearing RTE_DISTRIB_RETURN_BUF flag and allowing use in
the future if worker requests any new packets.
5) Do not allow to: send or add to backlog any packets for not
active workers. Such workers are also ignored if matched.
6) Adjust calls to handle_returns() and tags matching procedure
to react for possible activation deactivation of workers.

The flag "dev_started" is not changed anymore in "rte_eth_dev_close()".
In case the "dev_stop" function is called from "dev_close",
bypassing "rte_eth_dev_stop()" API,
the "dev_started" state must be explicitly reset in the PMD
in order to keep the same behaviour.

ethdev: introduce Rx buffer split
The DPDK datapath in the transmit direction is very flexible.
An application can build the multi-segment packet and manages
almost all data aspects - the memory pools where segments
are allocated from, the segment lengths, the memory attributes
like external buffers, registered for DMA, etc.
In the receiving direction, the datapath is much less flexible,
an application can only specify the memory pool to configure the
receiving queue and nothing more. In order to extend receiving
datapath capabilities it is proposed to add the way to provide
extended information how to split the packets being received.
The new offload flag RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT in device
capabilities is introduced to present the way for PMD to report to
application about supporting Rx packet split to configurable
segments. Prior invoking the rte_eth_rx_queue_setup() routine
application should check RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT flag.
The following structure is introduced to specify the Rx packet
segment for RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT offload:
struct rte_eth_rxseg_split {
struct rte_mempool *mp; /* memory pools to allocate segment from */
uint16_t length; /* segment maximal data length,
configures "split point" */
uint16_t offset; /* data offset from beginning
of mbuf data buffer */
uint32_t reserved; /* reserved field */
};
The segment descriptions are added to the rte_eth_rxconf structure:
rx_seg - pointer the array of segment descriptions, each element
describes the memory pool, maximal data length, initial
data offset from the beginning of data buffer in mbuf.
This array allows to specify the different settings for
each segment in individual fashion.
rx_nseg - number of elements in the array
If the extended segment descriptions is provided with these new
fields the mp parameter of the rte_eth_rx_queue_setup must be
specified as NULL to avoid ambiguity.
There are two options to specify Rx buffer configuration:
- mp is not NULL, rrx_conf.rx_nseg is zero, it is compatible
configuration, follows existing implementation, provides
the single pool and no description for segment sizes
and offsets.
- mp is NULL, rx_conf.rx_seg is not NULL, rx_conf.rx_nseg is not
zero, it provides the extended configuration, individually for
each segment.
f the Rx queue is configured with new settings the packets being
received will be split into multiple segments pushed to the mbufs
with specified attributes. The PMD will split the received packets
into multiple segments according to the specification in the
description array.
For example, let's suppose we configured the Rx queue with the
following segments:
seg0 - pool0, len0=14B, off0=2
seg1 - pool1, len1=20B, off1=128B
seg2 - pool2, len2=20B, off2=0B
seg3 - pool3, len3=512B, off3=0B
The packet 46 bytes long will look like the following:
seg0 - 14B long @ RTE_PKTMBUF_HEADROOM + 2 in mbuf from pool0
seg1 - 20B long @ 128 in mbuf from pool1
seg2 - 12B long @ 0 in mbuf from pool2
The packet 1500 bytes long will look like the following:
seg0 - 14B @ RTE_PKTMBUF_HEADROOM + 2 in mbuf from pool0
seg1 - 20B @ 128 in mbuf from pool1
seg2 - 20B @ 0 in mbuf from pool2
seg3 - 512B @ 0 in mbuf from pool3
seg4 - 512B @ 0 in mbuf from pool3
seg5 - 422B @ 0 in mbuf from pool3
The offload RTE_ETH_RX_OFFLOAD_SCATTER must be present and
configured to support new buffer split feature (if rx_nseg
is greater than one).
The split limitations imposed by underlying PMD is reported
in the new introduced rte_eth_dev_info->rx_seg_capa field.
The new approach would allow splitting the ingress packets into
multiple parts pushed to the memory with different attributes.
For example, the packet headers can be pushed to the embedded
data buffers within mbufs and the application data into
the external buffers attached to mbufs allocated from the
different memory pools. The memory attributes for the split
parts may differ either - for example the application data
may be pushed into the external memory located on the dedicated
physical device, say GPU or NVMe. This would improve the DPDK
receiving datapath flexibility with preserving compatibility
with existing API.

app/testpmd: add commands for tunnel offload
Tunnel Offload API provides hardware independent, unified model
to offload tunneled traffic. Key model elements are:
- apply matches to both outer and inner packet headers
during entire offload procedure;
- restore outer header of partially offloaded packet;
- model is implemented as a set of helper functions.
Implementation details:
* Create application tunnel:
flow tunnel create <port> type <tunnel type>
On success, the command creates application tunnel object and returns
the tunnel descriptor. Tunnel descriptor is used in subsequent flow
creation commands to reference the tunnel.
* Create tunnel steering flow rule:
tunnel_set <tunnel descriptor> parameter used with steering rule
template.
* Create tunnel matching flow rule:
tunnel_match <tunnel descriptor> used with matching rule template.
* If tunnel steering rule was offloaded, outer header of a partially
offloaded packet is restored after miss.

ethdev: add tunnel offload model
rte_flow API provides the building blocks for vendor-agnostic flow
classification offloads. The rte_flow "patterns" and "actions"
primitives are fine-grained, thus enabling DPDK applications the
flexibility to offload network stacks and complex pipelines.
Applications wishing to offload tunneled traffic are required to use
the rte_flow primitives, such as group, meta, mark, tag, and others to
model their high-level objects. The hardware model design for
high-level software objects is not trivial. Furthermore, an optimal
design is often vendor-specific.
When hardware offloads tunneled traffic in multi-group logic,
partially offloaded packets may arrive to the application after they
were modified in hardware. In this case, the application may need to
restore the original packet headers. Consider the following sequence:
The application decaps a packet in one group and jumps to a second
group where it tries to match on a 5-tuple, that will miss and send
the packet to the application. In this case, the application does not
receive the original packet but a modified one. Also, in this case,
the application cannot match on the outer header fields, such as VXLAN
vni and 5-tuple.
There are several possible ways to use rte_flow "patterns" and
"actions" to resolve the issues above. For example:
1 Mapping headers to a hardware registers using the
rte_flow_action_mark/rte_flow_action_tag/rte_flow_set_meta objects.
2 Apply the decap only at the last offload stage after all the
"patterns" were matched and the packet will be fully offloaded.
Every approach has its pros and cons and is highly dependent on the
hardware vendor. For example, some hardware may have a limited number
of registers while other hardware could not support inner actions and
must decap before accessing inner headers.
The tunnel offload model resolves these issues. The model goals are:
1 Provide a unified application API to offload tunneled traffic that
is capable to match on outer headers after decap.
2 Allow the application to restore the outer header of partially
offloaded packets.
The tunnel offload model does not introduce new elements to the
existing RTE flow model and is implemented as a set of helper
functions.
For the application to work with the tunnel offload API it
has to adjust flow rules in multi-table tunnel offload in the
following way:
1 Remove explicit call to decap action and replace it with PMD actions
obtained from rte_flow_tunnel_decap_and_set() helper.
2 Add PMD items obtained from rte_flow_tunnel_match() helper to all
other rules in the tunnel offload sequence.
VXLAN Code example:
Assume application needs to do inner NAT on the VXLAN packet.
The first rule in group 0:
flow create <port id> ingress group 0
pattern eth / ipv4 / udp dst is 4789 / vxlan / end
actions {pmd actions} / jump group 3 / end
The first VXLAN packet that arrives matches the rule in group 0 and
jumps to group 3. In group 3 the packet will miss since there is no
flow to match and will be sent to the application. Application will
call rte_flow_get_restore_info() to get the packet outer header.
Application will insert a new rule in group 3 to match outer and inner
headers:
flow create <port id> ingress group 3
pattern {pmd items} / eth / ipv4 dst is 172.10.10.1 /
udp dst 4789 / vxlan vni is 10 /
ipv4 dst is 184.1.2.3 / end
actions set_ipv4_dst 186.1.1.1 / queue index 3 / end
Resulting of the rules will be that VXLAN packet with vni=10, outer
IPv4 dst=172.10.10.1 and inner IPv4 dst=184.1.2.3 will be received
decapped on queue 3 with IPv4 dst=186.1.1.1
Note: The packet in group 3 is considered decapped. All actions in
that group will be done on the header that was inner before decap. The
application may specify an outer header to be matched on. It's PMD
responsibility to translate these items to outer metadata.

ethdev: allow negative values in flow rule types
RTE flow items & actions use positive values in item & action type.
Negative values are reserved for PMD private types. PMD
items & actions usually are not exposed to application and are not
used to create RTE flows.
The patch allows applications with access to PMD flow
items & actions ability to integrate RTE and PMD items & actions
and use them to create flow rule.
RTE flow item or action conversion library accepts positive known
element types with predefined sizes only. Private PMD items and
actions do not fit into this scheme because PMD type values are
negative, each PMD has it's own types numeration and element types and
their sizes are not visible at RTE level. To resolve these
limitations the patch proposes this solution:
1. PMD can expose elements of pointer size only. RTE flow
conversion functions will use pointer size for each configuration
object in private PMD element it processes;
2. RTE flow verification will not reject elements with negative type.

common/iavf: support VF with more than 16 queues
Currently there are limitations in the virthcnl.h interface that only
allow a maximum of 16 queues to be used by a VF driver. Add support in
virtchnl.h to allow a VF driver to request >16 queues. Also, the RSS
qregion size is currently assumed to be the max number of queues a VF
can request and/or is given on initialization. With larger VFs this
assumption can no longer be made, so add a new op to support querying
the max RSS qregion size.
In order to request more queues than the initially given queues the VF
driver needs to use the VIRTCHNL_OP_REQUEST_QUEUES opcode.
The VF is given more >16 queues it should use the new
VIRTCHNL_OP_GET_MAX_RSS_QREGION to determine its max qregion size. This
is needed to correctly configure the RSS LUT and/or configure filters
based on queue base/offset and queue region size.
If the VF is configuring >16 queues it should use the following opcodes
to configure the qeueus and interrupts after successfully requesting
them.
VIRTCHNL_OP_MAP_QUEUE_VECTOR
VIRTCHNL_OP_ENABLE_QUEUES_V2
VIRTCHNL_OP_DISABLE_QUEUES_V2
