6fe8ecc10c examples/ip_pipeline: fix IPv6 flow classification
IP Pipeline application with the configuration for Flow Classification
IPV6 did not instantiate.
Parse error in section "PIPELINE1": entry "dma_src_mask" too long

The dma_src_mask check in pipeline_passthrough_parse_args() is wrong.

This fix increases the length of dma_src_mask by 1 for NULL termination
and corrected the validation of dma_src_mask length.
This fix is also propagated to pipeline_fc_parse_args() for key_mask_str
validation.

399b2d4758 examples/ip_pipeline: fix action flow bulk command
Error while executing action flow bulk command
pipeline> p 1 action flow bulk ./config/action.txt
Command "action flow bulk" failed
pipeline>

The flow action entries are added successfully.
But the return value is not computed correctly.
Due to this, the error message appears on CLI.

The return value is computed with rsp->n_flows after rsp pointer is freed.
This fix computes the return value before rsp pointer is freed.

8673a3e8bd examples/ip_pipeline: add config diagram generator
This commit adds Python script for generating diagram of the application
configuration file. This script requires graphviz package to be installed
on the machine. The input config file is translated to an output file in
DOT syntax, which is then used to create the image file using graphviz.

To run the script, following command is used;

./diagram-generator.py -f <input configuration file>

Some optional arguments are as follows:
  -h, --help            show this help message and exit

fa667b46f5 examples/ip_pipeline: add core mappings script
This script parses the application configuration file and detects all the
pipelines specified therein, and then, it generates all the possible mappings
of those pipelines on the specified CPU core-list.

As a result, each of the possible pipeline-to-core mappings is saved as
separate output configuration file. For example- if input file is
edge_router_downstream.cfg with 3 pipeline (excluding pipeline 0) and
core-list is “1, 2”, following combinations will be generated-

Pipeline 1        Pipeline 2      Pipeline 3
Core = 1          Core = 1        Core = 2
Core = 1          Core = 2        Core = 1
Core = 2          Core = 1        Core = 1
Core = 2          Core = 2        Core = 1
Core = 2          Core = 1        Core = 2
Core = 1          Core = 2        Core = 2
Core = C1         Core = C1H      Core = C2
Core = C1         Core = C2       Core = C1H
Core = C2         Core = C1       Core = C1H

This script will help users to analyse the performance of application by
evaluating all the generated configuration files with different
pipelines-to-core mappings and obtaining the application configuration file
with best performance.

To run the script, issue the following command;

./pipeline-to-core-mapping.py -i <input_configuration_file> -pc "s<socket-id>c<core-id>"

Some optional arguments are as follows:
  -h, --help            show this help message and exit
  -ht {ON,OFF}, --hyper-thread {ON,OFF}
                        enable/disable hyper threading. default is ON
  -nO, --no-output-file
                        disable output config file generation. Output file
                        generation is enabled by default

5f0c5de435 examples/ip_pipeline: fix false cacheline sharing among threads
In ip_pipeline app, the structure app_thread_data needs to be aligned to
the cache line boundary as threads on different cpu cores are accessing
fields of the app->thread_data and having this structure not aligned on
cacheline boundary leads to false cacheline sharing.

1f277fa81a examples/ip_pipeline: assign MAC address to routing ports
As a result of tracking, output ports of routing pipelines are linked with
physical nic ports (potentially through other pipeline instances).
Thus, the mac addresses of the NIC ports are assigned to routing pipeline
out ports which are connected to them and are further used in routing table
entries instead of hardcoded default values.

760064838e examples/ip_pipeline: link routing output ports to devices
This commit implements tracking mechanism for linking routing pipeline
output ports to physical NIC ports.

Once all the pipelines of the application are initialised, mechanism is
invoked during post initialisation phase for relating routing pipeline
output with NIC ports by navigating through the intermediate pipelines,
if present.

The tracking functions of the pipelines which help in navigating through
the intermediate pipelines are moved from pipeline_<pipeline_name>_be.c
to pipeline_<pipeline_name>.c. All pipelines except passthrough pipelines
use default tracking function (pipeline/pipeline_common_fe.c).

966794fecb examples/ip_pipeline: support RSS
This patch enables rss (receive side scaling) per network interface
through the configuration file. The user can specify following
parameters in LINK section for enabling the rss feature - rss_qs,
rss_proto_ipv4, rss_proto_ipv6 and ip_proto_l2.

The "rss_qs" is mandatory parameter which indicates the queues to be
used for rss, while rest of the parameters are optional. When optional
parameters are not provided in the configuration file, default setting
(ETH_RSS_IPV4 | ETH_RSS_IPV6) is assumed for "rss_hf" field of the
rss_conf structure.

For example, following configuration can be applied for using the rss
on port 0 of the network interface;

[PIPELINE0]
type = MASTER
core = 0

[LINK0]
rss_qs = 0 1

[PIPELINE1]
type = PASS-THROUGH
core = 1
pktq_in = RXQ0.0 RXQ0.1 RXQ1.0
pktq_out = TXQ0.0 TXQ1.0 TXQ0.1

e5a1cd8a48 examples/ip_pipeline: clean up configuration parser
This commit adds following changes to configuration file parsing of
the ip pipeline application;

1. Parsing routines related to packet queues (pktq_in/out fields in the
PIPELINE section) and message queues (msgq_in/out fields of in the MSGQ
Section) are updated.

In the parsing routines, function "strtok_r()" is used for parsing the
string instead of manually checking the string termination, white
spaces, tabs etc., between the string tokens. Each call to strtok_r()
returns a pointer to a null-terminated string containing the next token.
If no more tokens are found, strtok_r() returns NULL. As a result of
using strtok_r(), the code size of the parsing routines is reduced
significantly.

2. Replace PARSER_PARAM_ADD_CHECK macro by more specific macros such as
PARSE_CHECK_DUPLICATE_SECTION, PARSE_CHECK_DUPLICATE_SECTION_EAL to detect
duplicate entries in the various sections of the configuration file

3. Add new macros PARSER_ERROR_NO_ELEMENTS and PARSE_ERROR_TOO_MANY_ELEMENTS
for detecting no element and more elements than allowed situations
respectively, in the section entry.

4. Add new macros APP_PARAM_ADD_LINK_FOR_RXQ, APP_PARAM_ADD_LINK_FOR_TXQ
and APP_PARAM_ADD_LINK_FOR_TM which add corresponding nic ports entry to
the application param structure while parsing rx/tx queues, TM (Traffic
Manager) port sections and pktq_in/out entries of pipeline sections

fe5d046213 examples/ip_pipeline: add pcap file dump
This patch add packet dumping feature to ip_pipeline. Output port type
SINK now supports dumping packets to PCAP file before releasing mbuf back
to mempool. This feature can be applied by specifying parameters in
configuration file as shown below:

[PIPELINE1]
type = PASS-THROUGH
core = 1
pktq_in = SOURCE0 SOURCE1
pktq_out = SINK0 SINK1
pcap_file_wr = /path/to/eth1.pcap /path/to/eth2.pcap
pcap_n_pkt_wr = 80 0

The configuration section "pcap_file_wr" contains full path and name of
the PCAP file which the packets will be dumped to. If multiple SINKs
exists, each shall have its own PCAP file path listed in this section,
separated by spaces. Multiple SINK ports shall NOT share same PCAP file to
be dumped.

The configuration section "pcap_n_pkt_wr" contains integer value(s)
and indicates the maximum number of packets to be dumped to the PCAP file.
If this value is "0", the "infinite" dumping mode will be used. If this
value is N (N > 0), the dumping will be finished when the number of
packets dumped to the file reaches N.

To enable PCAP dumping support to IP pipeline, the compiler option
CONFIG_RTE_PORT_PCAP must be set to 'y'. It is possible to disable this
feature by removing "pcap_file_wr" and "pcap_n_pkt_wr" lines from the
configuration file.

0e1e7d53ae examples/ip_pipeline: add pcap file source
This patch add PCAP file support to ip_pipeline. Input port type SOURCE
now supports loading specific PCAP file and sends the packets in it to
pipeline instance. The packets are then released by SINK output port. This
feature can be applied by specifying parameters in configuration file as
shown below;

[PIPELINE1]
type = PASS-THROUGH
core = 1
pktq_in = SOURCE0 SOURCE1
pktq_out = SINK0 SINK1
pcap_file_rd = /path/to/eth1.PCAP /path/to/eth2.PCAP
pcap_bytes_rd_per_pkt = 0 64

The configuration section "pcap_file_rd" contains full path and name of
the PCAP file to be loaded. If multiple SOURCEs exists, each shall have
its own PCAP file path listed in this section, separated by spaces.
Multiple SOURCE ports may share same PCAP file to be copied.

The configuration section "pcap_bytes_rd_per_pkt" contains integer value
and indicates the maximum number of bytes to be copied from each packet
in the PCAP file. If this value is "0", all packets in the file will be
copied fully; if the packet size is smaller than the assigned value, the
entire packet is copied. Same as "pcap_file_rd", every SOURCE shall have
its own maximum copy byte number.

To enable PCAP support to IP pipeline, the compiler option
CONFIG_RTE_PORT_PCAP must be set to 'y'. It is possible to disable PCAP
support by removing "pcap_file_rd" and "pcap_bytes_rd_per_pkt" lines
from the configuration file.

4c387fcdf7 pipeline: add new functions for action handlers
Two new pipeline API functions have been added to the library. The packet
hijack API function can be called by any input/output port or table action
handler to remove selected packets from the burst of packets read from one
of the pipeline input ports and then either send these packets out through
any pipeline output port or drop them.

Another packet drop API function can be used by the pipeline action
handlers (port in/out, table) to drop the packets selected using packet
mask. This function updates the drop statistics counters correctly.

88ac2fd99f pipeline: support packet redirection at action handlers
Currently, there is no mechanism that allows the pipeline ports (in/out)
and table action handlers to override the default forwarding decision
(as previously configured per input port or in the table entry). The port
(in/out) and table action handler prototypes have been changed to allow
pipeline action handlers (port in/out, table) to remove the selected
packets from the further pipeline processing and to take full ownership
for these packets. This feature will be helpful to implement functions
such as exception handling (e.g. TTL =0), load balancing etc.

4e14069328 examples/ip_pipeline: measure CPU utilization
This patch adds CPU utilization measurement and idle cycle rate
computation to packet framework. The measurement is done by measuring
the cycles spent while a thread pulls zero packet from RX queue. These
cycles are treated as idle cycles (or headroom). A CLI command is added
to display idle cycle rate of specific thread. The CLI command format is
shown as following:

t <thread_id> headroom

7f837dcc8f examples/ip_pipeline: add sample configurations and scripts
This patch includes the configuration and script files of the some
applications which can be built using DPDK Packet Framework. A
configuration file defines the application structure which include
packet processing stages (knowns as pipelines), their connectivity
and other parameters necessary to start and run the application. A
script file specifies CLI commands required for loading table entries
(rules/routes, etc). The configuration/script files for simple
applications such as l2 forwarding, l3 forwarding have been presented.
In addition, to demonstrate the use and inter-connectivity of various
pipeline modules (which are avilable in packet framework), a complex
packet processing workload i.e. edge router is considered. The
configuration of the pipeline stages used for upstream and downstream
flow processing has been specified separately in two configuration
files. All these configuration and script files don't affect the
compilation.
