Passing argument "&app->cmds[app->n_cmds]" of type "cmdline_parse_ctx_t *"

When first adding flow actions pipeline, some files were not pushed
to the repository by mistake. The original commit message is below.
Fixes: 9ef2593651 ("examples/ip_pipeline: add flow actions pipeline")
Flow actions pipeline is an extension of flow-classification pipeline.
Some of the operations of flow classification pipeline such as traffic
metering/marking(for e.g. Single Rate Three Color Marker (srTCM), Two
Rate Three Color Marker trTCM)), policer can be performed separately in
flow action pipeline to avoid excessive computational burden on the CPU
core running the flow-classification pipeline. The Flow action pipeline
implements various function such as traffic metering, policer, stats.
Traffic mettering can configured as per the required context, for
examples- per user, per traffic class or both. These contexts can be
applied by specifying parameters in configuration file as shown below;
[PIPELINE1]
type = FLOW_ACTIONS
core = 1
pktq_in = RXQ0.0 RXQ1.0 RXQ2.0 RXQ3.0
pktq_out = TXQ0.0 TXQ1.0 TXQ2.0 TXQ3.0
n_flows = 65536
n_meters_per_flow = 1
flow_id_offset = 158
ip_hdr_offset = 142
color_offset = 64
The entries of flow and dscp tables of flow actions pipeline can be
modified through command-line interface. The commands to add or delete
entries to the flow table, DSCP(differentiated services code point)
table and for statistics collection, etc have been included. The key
functions such as Traffic Metering/marking and policer functions have
been implemented as flow-table action handler.

l3fwd app expects PMDs to return packets whose L2 header is
16-byte aligned due to usage of _mm_load_si128()/_mm_store_si128()
intrinsics in the app. However, most of the protocol stacks expects
packets such that its IP/L3 header be aligned on a 16-byte boundary.
Based on the recommendations received on dpdk-dev, we are changing
the l3fwd app to use _mm_loadu_si128()/_mm_loadu_si128() so that the
address need not be 16-byte aligned and thereby preventing crash.
We have tested that there is no performance impact due to this

use-cases;

2.Double-tagged VLAN (Q-in-Q) packet enacapsulation
for the next-hop
3.MPLS encapsulation for the next-hop
4.Add colour (Traffic-class for QoS) to the MPLS tag
5.Classification action to select the input queue
of the hierarchical schedular (QoS)
The above proposed features can be enabled
(or disabled) through the parameters specified
in configuration file as below;
[PIPELINE0]
type = ROUTING
core = 1
pktq_in = RXQ0.0 RXQ1.0 RXQ2.0 RXQ3.0

(Q-in-Q, MPLS)for the next-hop. The CLI
commands for adding or deleting such entries
to LPM table have been implemented. Action

This patch implements a generic approach to
extract fields from the packet's header and
copying them to packet metadata. The fields
are selected at the desired offset on the basis
of the mask specified in application configuration
file. The extracted fields, for instance, can be
used to compute hash for the lookup table. This
feature exposes more flexibility to the users as
they will be able to employ new protocol headers
and specify the required fields to be extracted.
The above feature has been implemented as port_in
action handler of the passthrough pipeline. The
example of the configuration file for passthrough
pipeline is as below;

The working thread returns to polling mode immediately once it receives an
interrupt notification caused by the incoming packets.

the rx interrupt yet. Now only ixgbe(pf/vf) and igb support it.

when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'

Currently for mbufs with refcnt, we cannot free mbufs with external memory
buffers (ie. vhost zero copy), as they are recognized as indirect
attached mbufs and therefore we free the direct mbuf it points to,
resulting in an error in the case of external memory buffers.
We solve the issue by introducing the IND_ATTACHED_MBUF flag, which indicates
that the mbuf is an indirect attached mbuf pointing to another mbuf.
When we free an mbuf, we only free the direct mbuf if the flag is set.
Freeing an mbuf with external buffer is the same as freeing a non attached mbuf.
The flag is set during attach and clear on detach.
So in the case of vhost zero copy where we have mbufs with external
buffers, by default we just free the mbuf and it is up to the user to deal with
the external buffer.
This patch would allow the removal of the RTE_MBUF_REFCNT config option,
setting refcnt for all mbufs permanently.
The patch also modifies the vhost example as it was using the
RTE_MBUF_INDIRECT macro to detect if it was an mbuf with external buffer.

* Workers dequeue mbufs from ring, do some 'work' and enqueue mbufs in

To make it possible for the user to decide about performance/space trade-off -
new parameter for build config structure (max_size) is introduced.
Setting it to the value greater than zero, instructs rte_acl_build() to:
- make sure that size of RT table wouldn't exceed given value.
- attempt to minimise number of tries in the table.
Setting it to zero maintains current behaviour.

When using test-pmd with flow director in FreeBSD, the application will
segfault/Bus error while parsing the command-line. This is due to how
each commands result structure is represented during parsing, where the offsets
for each tokens value is stored in a character array(char result_buf[BUFSIZ])
in cmdline_parse()(./lib/librte_cmdline/cmdline_parse.c).
The overflow occurs where BUFSIZ is less than the size of a commands result
structure, in this case "struct cmd_pkt_filter_result"
(app/test-pmd/cmdline.c) is 1088 bytes and BUFSIZ on FreeBSD is 1024 bytes as
opposed to 8192 bytes on Linux.
The problem can be reproduced by running test-pmd on FreeBSD:
./testpmd -c 0x3 -n 4 -- -i --portmask=0x3 --pkt-filter-mode=perfect
And adding a filter:
add_perfect_filter 0 udp src 192.168.0.0 1024 dst 192.168.0.0 1024 flexbytes
0x800 vlan 0 queue 0 soft 0x17
This patch removes the OS dependency on BUFSIZ and defines and uses a
library #define CMDLINE_PARSE_RESULT_BUFSIZE 8192
Added boundary checking to ensure this buffer size cannot overflow, with
an error message being produced.

Some of the NICs supported by DPDK have a possibility to accelerate TCP
traffic by using segmentation offload. The application prepares a packet
with valid TCP header with size up to 64K and deleguates the
segmentation to the NIC.
Implement the generic part of TCP segmentation offload in rte_mbuf. It
introduces 2 new fields in rte_mbuf: l4_len (length of L4 header in bytes)
and tso_segsz (MSS of packets).
To delegate the TCP segmentation to the hardware, the user has to:
- set the PKT_TX_TCP_SEG flag in mbuf->ol_flags (this flag implies
PKT_TX_TCP_CKSUM)
- set the flag PKT_TX_IPV4 or PKT_TX_IPV6
- set PKT_TX_IP_CKSUM if it's IPv4, and set the IP checksum to 0 in
the packet
- fill the mbuf offload information: l2_len, l3_len, l4_len, tso_segsz
- calculate the pseudo header checksum without taking ip_len in account,
and set it in the TCP header, for instance by using
rte_ipv4_phdr_cksum(ip_hdr, ol_flags)
The API is inspired from ixgbe hardware (the next commit adds the
support for ixgbe), but it seems generic enough to be used for other
hw/drivers in the future.
This commit also reworks the way l2_len and l3_len are used in igb
and ixgbe drivers as the l2_l3_len is not available anymore in mbuf.

Provides a small sample application(guest_vm_power_mgr) to run on a VM.
The application is run by providing a core mask(-c) and number of memory
channels(-n). The core mask corresponds to the number of lcore channels to
attempt to open. A maximum of 64 channels per VM is allowed. The channels must
be monitored by the host.
After successful initialisation a CPU frequency command can be sent to the host
using:
set_cpu_freq <lcore_num> <up|down|min|max>.

A wrapper around librte_power(using ACPI cpufreq), providing locking around the
non-threadsafe library, allowing for frequency changes based on core masks and
core numbers from both the CLI thread and epoll monitor thread.

The CLI is used for administrating the channel monitor and manager and
manually setting the CPU frequency on the host.
Supports the following commands:
add_vm [Mul-choice STRING]: add_vm|rm_vm <name>, add a VM for subsequent
operations with the CLI or remove a previously added VM from the VM Power
Manager
rm_vm [Mul-choice STRING]: add_vm|rm_vm <name>, add a VM for subsequent
operations with the CLI or remove a previously added VM from the VM Power
Manager
add_channels [Fixed STRING]: add_channels <vm_name> <list>|all, add
communication channels for the specified VM, the virtio channels must be
enabled in the VM configuration(qemu/libvirt) and the associated VM must be
active. <list> is a comma-separated list of channel numbers to add, using the
keyword 'all' will attempt to add all channels for the VM
set_channel_status [Fixed STRING]:
set_channel_status <vm_name> <list>|all enabled|disabled, enable or disable
the communication channels in list(comma-separated) for the specified VM,
alternatively list can be replaced with keyword 'all'. Disabled channels will
still receive packets on the host, however the commands they specify will be
ignored. Set status to 'enabled' to begin processing requests again.
show_vm [Fixed STRING]: show_vm <vm_name>, prints the information on the
specified VM(s), the information lists the number of vCPUS, the pinning to
pCPU(s) as a bit mask, along with any communication channels associated with
each VM
show_cpu_freq_mask [Fixed STRING]: show_cpu_freq_mask <mask>, Get the current
frequency for each core specified in the mask
set_cpu_freq_mask [Fixed STRING]: set_cpu_freq <core_mask> <up|down|min|max>,
Set the current frequency for the cores specified in <core_mask> by scaling
each up/down/min/max.
show_cpu_freq [Fixed STRING]: Get the current frequency for the specified core
set_cpu_freq [Fixed STRING]: set_cpu_freq <core_num> <up|down|min|max>,
Set the current frequency for the specified core by scaling up/down/min/max
quit [Fixed STRING]: close the application

The manager is responsible for adding communications channels to the Monitor
thread, tracking and reporting VM state and employs the libvirt API for
synchronization with the KVM Hypervisor. The manager interacts with the
Hypervisor to discover the mapping of virtual CPUS(vCPUs) to the host
physical CPUS(pCPUs) and to inspect the VM running state.
The manager provides the following functionality to the CLI:
1) Connect to a libvirtd instance, default: qemu:///system
2) Add a VM to an internal list, each VM is identified by a "name" which must
correspond a valid libvirt Domain Name.
3) Add communication channels associated with a VM to the epoll based Monitor
thread.
The channels must exist and be in the form of:
/tmp/powermonitor/<vm_name>.<channel_number>. Each channel is a
Virtio-Serial endpoint configured as an AF_UNIX file socket and opened in
non-blocking mode.
Each VM can have a maximum of 64 channels associated with it.
4) Disable or re-enable VM communication channels, channels once added to the
Monitor thread remain in that threads control, however acting on channel
requests can be disabled and renabled via CLI.
The monitor is an epoll based infinite loop running in a separate thread that
waits on channel events from VMs and calls the corresponding functions. Channel
definitions from the manager are registered via the epoll event opaque pointer
when calling epoll_ctl(EPOLL_CTL_ADD), this allows for obtaining the channels
file descriptor for reading EPOLLIN events and mapping the vCPU to pCPU(s)
associated with a request from a particular VM.

This is a very simple example app for doing packet forwarding with the
Intel DPDK. It's designed to serve as a start point for people new to
the Intel DPDK and who want to develop a new app.
Therefore it's meant to:
* have as good a performance out-of-the-box as possible, using the
best-known settings for configuring the PMDs, so that any new apps can
be based off it.
* be kept as short as possible to make it easy to understand it and get
started with it.

A new sample app that shows the usage of the distributor library. This
app works as follows:
* An RX thread runs which pulls packets from each ethernet port in turn
and passes those packets to worker using a distributor component.
* The workers take the packets in turn, and determine the output port
for those packets using basic l2forwarding doing an xor on the source
port id.
* The RX thread takes the returned packets from the workers and enqueue
those packets into an rte_ring structure.
* A TX thread pulls the packets off the rte_ring structure and then
sends each packet out the output port specified previously by the worker
* Command-line option support provided only for portmask.
