The miss is spotted with devtools/check-maintainers.sh.

As this test file is related to eventdev, they should both

f3cb39e882 devtools: add script to find duplicated includes
Based on Stephen's idea (originally implemented in a Perl script),
this is a shell script to find duplicated includes in a file.
It looks for all the .c and .h files of the git repository.

It is fast enough because automatically well parallelized.

a46f8d584e net/failsafe: add fail-safe PMD
Introduce the fail-safe poll mode driver initialization and enable its
build infrastructure.

This PMD allows for applications to benefit from true hot-plugging
support without having to implement it.

It intercepts and manages Ethernet device removal events issued by
slave PMDs and re-initializes them transparently when brought back.
It also allows defining a contingency to the removal of a device, by
designating a fail-over device that will take on transmitting operations
if the preferred device is removed.

Applications only see a fail-safe instance, without caring for
underlying activity ensuring their continued operations.

db75c7af19 examples/vhost_scsi: introduce a new sample app
vhost-user protocol is common to many virtio devices, such as
virtio_net/virtio_scsi/virtio_blk. Since DPDK vhost library
removed the NET specific data structures, the vhost library
is common to other virtio devices, such as virtio-scsi.

Here we introduce a simple memory based block device that
can be presented to Guest VM through vhost-user-scsi-pci
controller. Similar with vhost-net, the sample application
will process the I/Os sent via virt rings.

Add a bunch of unit tests, to ensure that the service
core functions are operating as expected.

As part of these tests a dummy service is registered which
allows identifying if a service callback has been invoked
by using the CPU tick counter. This allows identifying if
functions to start and stop service lcores are actually having
effect.

5d109deffa ethdev: add traffic management API
This patch introduces the generic ethdev API for the traffic manager
capability, which includes: hierarchical scheduling, traffic shaping,
congestion management, packet marking.

Main features:
- Exposed as ethdev plugin capability (similar to rte_flow)
- Capability query API per port, per level and per node
- Scheduling algorithms: Strict Priority (SP), Weighed Fair Queuing (WFQ)
- Traffic shaping: single/dual rate, private (per node) and shared (by
  multiple nodes) shapers
- Congestion management for hierarchy leaf nodes: algorithms of tail drop,
  head drop, WRED; private (per node) and shared (by multiple nodes) WRED
  contexts
- Packet marking: IEEE 802.1q (VLAN DEI), IETF RFC 3168 (IPv4/IPv6 ECN for
  TCP and SCTP), IETF RFC 2597 (IPv4 / IPv6 DSCP)

e996506a1c lib/gro: add Generic Receive Offload API framework
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.

adb5d5486c examples/eventdev_pipeline_sw_pmd: add sample app
This commit adds a sample app for the eventdev library.
The app has been tested with DPDK 17.05-rc2, hence this
release (or later) is recommended.

The sample app showcases a pipeline processing use-case,
with event scheduling and processing defined per stage.
The application receives traffic as normal, with each
packet traversing the pipeline. Once the packet has
been processed by each of the pipeline stages, it is
transmitted again.

The app provides a framework to utilize cores for a single
role or multiple roles. Examples of roles are the RX core,
TX core, Scheduling core (in the case of the event/sw PMD),
and worker cores.

Various flags are available to configure numbers of stages,
cycles of work at each stage, type of scheduling, number of
worker cores, queue depths etc. For a full explaination,
please refer to the documentation.

themselves are statistics that are not generated by PMDs, and
hence are not reported via ethdev extended statistics.

Metric information is populated using a push model, where
producers update the values contained within the metric
library by calling an update function on the relevant metrics.
Consumers receive metric information by querying the central
metric data, which is held in shared memory.

71f2384328 eventdev: introduce event driven programming model
In a polling model, lcores poll ethdev ports and associated
rx queues directly to look for packet. In an event driven model,
by contrast, lcores call the scheduler that selects packets for
them based on programmer-specified criteria. Eventdev library
adds support for event driven programming model, which offer
applications automatic multicore scaling, dynamic load balancing,
pipelining, packet ingress order maintenance and
synchronization services to simplify application packet processing.

By introducing event driven programming model, DPDK can support
both polling and event driven programming models for packet processing,
and applications are free to choose whatever model
(or combination of the two) that best suits their needs.

This patch adds the eventdev specification header file.
