4cd69cc855 doc: clarify port hotplug in testpmd
Port needs to be stopped and then closed before it can be detached,
but the documentation was only saying to close the port.

Also, both sections for port detaching and attaching has been reformatted
slightly, to show clearly how to use the commands.

66888a37ff examples/quota_watermark: fix memory overflow
qw app at its init stage reserve 2*sizeof(int) memory space for quota
and low_watermark shared variables, but both apps (qw and qwctl) assign
wrong address for low_watermark pointer (out of reserved memzone space)
due to wrong pointer arithmetic.

CID 30709 : Extra sizeof expression (SIZEOF_MISMATCH)
suspicious_pointer_arithmetic: Adding 4UL /* sizeof (int) */ to pointer
(unsigned int *)(*qw_memzone).addr of type unsigned int * is suspicious
because adding an integral value to this pointer automatically scales
that value by the size, 4 bytes, of the pointed-to type, unsigned int.
Most likely, sizeof (int) is extraneous and should be replaced with 1.

65067473d0 examples/ip_pipeline: add sample configs for various layers
The sample configuration file demonstrates that network layer components such
as TCP, UDP, ICMP etc, can be easily integrated into ip pipeline infrastructure.
Similarily, various other functionalities such as IP Reassembly for input
traffic with local destination and IP Fragmentation to enforce the MTU for
the routed output traffic, can be added using SWQs enabled with
reassembly and fragmentation features.

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

ca173a9095 ivshmem: add all memzones of mempool to metadata
Mempool consist of multiple memzones, at least from two of them.
ivshmem assumes mempool and elements are all in same memzone.

Updating code to add all memzones when a mempool added.

Fixes: d1d914ebbc ("mempool: allocate in several memory chunks by default")

fc552cfb14 ivshmem: document a potential crash in rte_ring
Commit 4768c475 added a pointer to the memzone in rte_ring. However,
all memzones are residing in local mem_config, therefore accessing
the memzone pointer inside the guest in an IVSHMEM-shared rte_ring
will cause segmentation fault. This issue is unlikely to ever get
fixed, as this would require lots of changes for very little benefit,
therefore we're documenting this limitation instead.

a2113ebba5 ivshmem: fix overlap detection
Partial revert of an earlier ill-conceived "fix".
Adjacent segments can never be considered overlapping because we
are not comparing ends to starts, but rather starts to starts.
Therefore the earlier fix was wrong (plus it also had a typo).

Fixes: d6cf31419e ("ivshmem: avoid infinite loop when concatenating segments")
