The rte_stack library provides an API for configuration and use of a
bounded stack of pointers. Push and pop operations are MT-safe, allowing
concurrent access, and the interface supports pushing and popping multiple
pointers at a time.
The library's interface is modeled after another DPDK data structure,
rte_ring, and its lock-based implementation is derived from the stack
mempool handler. An upcoming commit will migrate the stack mempool handler
to rte_stack.

Since compat library is only a single header, we can easily move it into
the EAL common headers instead of tracking it separately. The downside of
this is that it becomes a little more difficult to have any libs that are
built before EAL depend on it. Thankfully, this is not a major problem as
the only library which uses rte_compat.h and is built before EAL (kvargs)
already has the path to the compat.h header file explicitly called out as
an include path.
However, to ensure that we don't hit problems later with this, we can add
EAL common headers folder to the global include list in the meson build
which means that all common headers can be safely used by all libraries, no
matter what their build order.
As a side-effect, this patch also fixes an issue with building on BSD using
meson, due to compat lib no longer needing to be listed as a dependency.

A device which can be scanned on an installed bus (pci, fslmc, ...)
or instantiated through devargs, can be interfaced using
standardized APIs just like other standardized devices.
This library introduces an API set which can be plugged on the
northbound side to the application layer, and on the southbound side
to the driver layer.
The APIs of rawdev library exposes some generic operations which can
enable configuration and I/O with the raw devices. Using opaque
data (pointer) as API arguments, library allows a high flexibility
for application and driver implementation.
This patch introduces basic device operations like start, stop, reset,

This patch adds GSO support for TCP/IPv4 packets. Supported packets
may include a single VLAN tag. TCP/IPv4 GSO doesn't check if input
packets have correct checksums, and doesn't update checksums for
output packets (the responsibility for this lies with the application).
Additionally, TCP/IPv4 GSO doesn't process IP fragmented packets.
TCP/IPv4 GSO uses two chained MBUFs, one direct MBUF and one indrect
MBUF, to organize an output packet. Note that we refer to these two
chained MBUFs as a two-segment MBUF. The direct MBUF stores the packet
header, while the indirect mbuf simply points to a location within the
original packet's payload. Consequently, use of the GSO library requires
multi-segment MBUF support in the TX functions of the NIC driver.
If a packet is GSO'd, TCP/IPv4 GSO reduces its MBUF refcnt by 1. As a
result, when all of its GSOed segments are freed, the packet is freed
automatically.

Generic Segmentation Offload (GSO) is a SW technique to split large
packets into small ones. Akin to TSO, GSO enables applications to
operate on large packets, thus reducing per-packet processing overhead.
To enable more flexibility to applications, DPDK GSO is implemented
as a standalone library. Applications explicitly use the GSO library
to segment packets. To segment a packet requires two steps. The first
is to set proper flags to mbuf->ol_flags, where the flags are the same
as that of TSO. The second is to call the segmentation API,
rte_gso_segment(). This patch introduces the GSO API framework to DPDK.
rte_gso_segment() splits an input packet into small ones in each
invocation. The GSO library refers to these small packets generated
by rte_gso_segment() as GSO segments. Each of the newly-created GSO
segments is organized as a two-segment MBUF, where the first segment is a
standard MBUF, which stores a copy of packet header, and the second is an
indirect MBUF which points to a section of data in the input packet.
rte_gso_segment() reduces the refcnt of the input packet by 1. Therefore,
when all GSO segments are freed, the input packet is freed automatically.
Additionally, since each GSO segment has multiple MBUFs (i.e. 2 MBUFs),
the driver of the interface which the GSO segments are sent to should
support to transmit multi-segment packets.
The GSO framework clears the PKT_TX_TCP_SEG flag for both the input
packet, and all produced GSO segments in the event of success, since
segmentation in hardware is no longer required at that point.

Membership library is an extension and generalization of a traditional
filter (for example Bloom Filter and cuckoo filter) structure.
In general, the Membership library is a data structure that provides a
"set-summary" and responds to set-membership queries of whether a
certain element belongs to a set(s). A membership test for an element
will return the set this element belongs to or not-found if the
element is never inserted into the set-summary.
The results of the membership test are not 100% accurate. Certain
false positive or false negative probability could exist. However,
comparing to a "full-blown" complete list of elements, a "set-summary"
is memory efficient and fast on lookup.

Generic Receive Offload (GRO) is a widely used SW-based offloading
technique to reduce per-packet processing overhead. It gains
performance by reassembling small packets into large ones. This
patchset is to support GRO in DPDK. To support GRO, this patch
implements a GRO API framework.
To enable more flexibility to applications, DPDK GRO is implemented as
a user library. Applications explicitly use the GRO library to merge
small packets into large ones. DPDK GRO provides two reassembly modes.
One is called lightweight mode, the other is called heavyweight mode.
If applications want to merge packets in a simple way and the number
of packets is relatively small, they can use the lightweight mode.
If applications need more fine-grained controls, they can choose the
heavyweight mode.
rte_gro_reassemble_burst is the main reassembly API which is used in
lightweight mode and processes N packets at a time. For applications,
performing GRO in lightweight mode is simple. They just need to invoke
rte_gro_reassemble_burst. Applications can get GROed packets as soon as
rte_gro_reassemble_burst returns.
rte_gro_reassemble is the main reassembly API which is used in
heavyweight mode and tries to merge N inputted packets with the packets
in GRO reassembly tables. For applications, performing GRO in heavyweight
mode is relatively complicated. Before performing GRO, applications need
to create a GRO context object, which keeps reassembly tables of
desired GRO types, by rte_gro_ctx_create. Then applications can use
rte_gro_reassemble to merge packets. The GROed packets are in the
reassembly tables of the GRO context object. If applications want to get
them, applications need to manually flush them by flush API.

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:
- First, because it uses perfect hashing, it does not store
the key itself and hence lookup performance is not dependent
on the key size.
- Second, the target/value can be any arbitrary value hence
the system designer and/or operator can better optimize service rates
and inter-cluster network traffic locating.
- Third, since the storage requirement is much smaller than a hash-based
flow table (i.e. better fit for CPU cache), EFD can scale to
millions of flow keys.
Finally, with current optimized library implementation performance
is fully scalable with number of CPU cores.

The librte_pdump library provides a framework for
packet capturing in dpdk. The library provides set of
APIs to initialize the packet capture framework, to
enable or disable the packet capture, and to uninitialize
it.
The librte_pdump library works on a client/server model.
The server is responsible for enabling or disabling the
packet capture and the clients are responsible
for requesting the enabling or disabling of the packet
capture.
Enabling APIs are supported with port, queue, ring and
mempool parameters. Applications should pass on this information
to get the packets from the dpdk ports.
For enabling requests from applications, library creates the client
request containing the mempool, ring, port and queue information and
sends the request to the server. After receiving the request, server
registers the Rx and Tx callbacks for all the port and queues.
After the callbacks registration, registered callbacks will get the
Rx and Tx packets. Packets then will be copied to the new mbufs that
are allocated from the user passed mempool. These new mbufs then will
be enqueued to the application passed ring. Applications need to dequeue
the mbufs from the rings and direct them to the devices like
pcap vdev for viewing the packets outside of the dpdk
using the packet capture tools.
For disabling requests, library creates the client request containing
the port and queue information and sends the request to the server.
After receiving the request, server removes the Rx and Tx callback
for all the port and queues.
