33e71acf3d drivers: remove octeontx2 drivers
As per the deprecation notice,  In the view of enabling unified driver
for octeontx2(cn9k)/octeontx3(cn10k), removing drivers/octeontx2
drivers and replace with drivers/cnxk/ which
supports both octeontx2(cn9k) and octeontx3(cn10k) SoCs.

This patch does the following

- Replace drivers/common/octeontx2/ with drivers/common/cnxk/
- Replace drivers/mempool/octeontx2/ with drivers/mempool/cnxk/
- Replace drivers/net/octeontx2/ with drivers/net/cnxk/
- Replace drivers/event/octeontx2/ with drivers/event/cnxk/
- Replace drivers/crypto/octeontx2/ with drivers/crypto/cnxk/
- Rename config/arm/arm64_octeontx2_linux_gcc as
  config/arm/arm64_cn9k_linux_gcc
- Update the documentation and MAINTAINERS to reflect the same.
- Change the reference to OCTEONTX2 as OCTEON 9. Old release notes and
the kernel related documentation is not accounted for this change.

54dcfdee85 drivers/raw: standardize naming
The driver names for rawdevs were both different in make and meson builds
and were non-standard in the make version in that some included "rawdev" in
the name while others didn't.

Therefore, for global consistency of naming, we can use "rte_rawdev" rather
than "rte_pmd" for the prefix for the libraries. While most other driver
categories use "rte_pmd" as a prefix, there is precedent for this in the
mempool drivers use "rte_mempool" as a prefix.

505f1fe426 net/mlx5: add Tx devargs
This patch introduces new mlx5 PMD devarg options:

- txq_inline_min - specifies minimal amount of data to be inlined into
  WQE during Tx operations. NICs may require this minimal data amount
  to operate correctly. The exact value may depend on NIC operation
  mode, requested offloads, etc.

- txq_inline_max - specifies the maximal packet length to be completely
  inlined into WQE Ethernet Segment for ordinary SEND method. If packet
  is larger the specified value, the packet data won't be copied by the
  driver at all, data buffer is addressed with a pointer. If packet
  length is less or equal all packet data will be copied into WQE.

- txq_inline_mpw - specifies the maximal packet length to be completely
  inlined into WQE for Enhanced MPW method.

Driver documentation is also updated.

f14a945915 net/pcap: remove Rx queue argument necessity
Previously in the PCAP PMD queues has to be defined as RxQ and TxQ
pairs, even if the need is only Rx or only Tx:
 "--vdev net_pcap0,tx_pcap=tx.pcap,rx_pcap=rx.pcap"

Following commit enabled only providing Rx queue, and if Tx queue is
not provided PMD drops the Tx packets automatically:
Commit a3f5252e5c ("net/pcap: enable infinitely Rx a pcap file")
 "--vdev net_pcap0,rx_pcap=rx.pcap"

This commit enables same thing for Rx queue, user no more have to
provide a Rx queue (rx_iface or rx_pcap), for this case a dummy Rx
burst function is used which doesn't return any packet at all:
 "--vdev net_pcap0,tx_pcap=tx.pcap"

This makes only saving packets to a pcap file use case easy.

When both Rx and Tx queues are missing PMD will return an error.
(Single interface is still supported: "--vdev net_pcap0,iface=eth0")

f15db67df0 net/mlx5: accelerate DV flow counter query
All the DV counters are cashed in the PMD memory and are contained in
pools which are contained in containers according to the counters
allocation type - batch or single.

Currently, the flow counter query is done synchronously in pool
resolution means that on the user request a FW command is triggered to
read all the counters in the pool.

A new feature of devX to asynchronously read batch of flow counters
allows to accelerate the user query operation.

Using the DPDK host thread, the PMD periodically triggers asynchronous
query in pool resolution for all the counter pools and an interrupt is
triggered by the FW when the values are updated.
In the interrupt handler the pool counter values raw data is replaced
using a double buffer algorithm (very fast).
In the user query, the PMD just returns the last query values from the
PMD cache - no system-calls and FW commands are triggered from the user
control thread on query operation!

More synchronization is added with the host thread:
        Container resize uses double buffer algorithm.
        Pools growing in container uses atomic operation.
        Pool query buffer replace uses a spinlock.
        Pool minimum devX counter ID uses atomic operation.

Enabled IP-in-IP tunnel type support on DV/DR flow engine.
This includes the following combination:
 - IPv4 over IPv4
 - IPv4 over IPv6
 - IPv6 over IPv4
 - IPv6 over IPv6

MLX5 NIC supports IP-in-IP tunnel via FLEX Parser so
need to make sure fw using FLEX Paser profile 0.

  mlxconfig -d <mst device> -y set FLEX_PARSER_PROFILE_ENABLE=0

The example testpmd commands would be:

- Match on IPv4 over IPv4 packets and do inner RSS:

  testpmd> flow create 0 ingress pattern eth / ipv4 proto is 0x04 /
           ipv4 / udp / end actions rss level 2 queues 0 1 2 3 end / end

- Match on IPv6 over IPv4 packets and do inner RSS:

  testpmd> flow create 0 ingress pattern eth / ipv4 proto is 0x29 /
           ipv6 / udp / end actions rss level 2 queues 0 1 2 3 end / end

e29fc44370 ip_frag: remove IP checkum offload flag
Currently PKT_TX_IP_CKSUM is being set into mbuf->ol_flags
during fragmentation and reassemble operation implicitly.
Because of this, application is forced to use checksum offload
whether it is supported by platform or not.

Also documentation does not provide any expected value of ol_flags
in returned mbuf (reassembled or fragmented) so application will never
come to know that which offloads are enabled. So transmission may be failed
for the platforms which does not support checksum offload.

Also, IPv6 does not contain any checksum field in header so setting
mbuf->ol_flags with PKT_TX_IP_CKSUM is itself invalid.

So removing mentioned flag from the library.

2173f3333b mcslock: add MCS queued lock implementation
If there are multiple threads contending, they all attempt to take the
spinlock lock at the same time once it is released. This results in a
huge amount of processor bus traffic, which is a huge performance
killer. Thus, if we somehow order the lock-takers so that they know who
is next in line for the resource we can vastly reduce the amount of bus
traffic.

This patch added MCS lock library. It provides scalability by spinning
on a CPU/thread local variable which avoids expensive cache bouncings.
It provides fairness by maintaining a list of acquirers and passing the
lock to each CPU/thread in the order they acquired the lock.

5f4ed3f058 eal: introduce random generator with upper bound
Add a function rte_rand_max() which generates an uniformly distributed
pseudo-random number less than a user-specified upper bound.

The commonly used pattern rte_rand() % SOME_VALUE creates biased
results (as in some values in the range are more frequently occurring
than others) if SOME_VALUE is not a power of 2.

3f002f0696 eal: replace libc-based random generation with LFSR
This commit replaces rte_rand()'s use of lrand48() with a DPDK-native
combined Linear Feedback Shift Register (LFSR) (also known as
Tausworthe) pseudo-random number generator.

This generator is faster and produces better-quality random numbers
than the linear congruential generator (LCG) of lib's lrand48(). The
implementation, as opposed to lrand48(), is multi-thread safe in
regards to concurrent rte_rand() calls from different lcore threads.
A LCG is still used, but only to seed the five per-lcore LFSR
sequences.

In addition, this patch also addresses the issue of the legacy
implementation only producing 62 bits of pseudo randomness, while the
API requires all 64 bits to be random.

This pseudo-random number generator is not cryptographically secure -
just like lrand48().

609e79841f examples/l3fwd-power: add telemetry mode
Add new telemetry mode support for l3fwd-power.
This is a standalone mode, in this mode l3fwd-power
does simple l3fwding along with calculating
empty polls, full polls, and busy percentage for
each forwarding core. The aggregation of these
values of all cores is reported as application
level telemetry to metric library for every 500ms from the
master core.

The busy percentage is calculated by recording the poll_count
and when the count reaches a defined value the total
cycles it took is measured and compared with minimum and maximum
reference cycles and busy rate is set according to either 0% or
50% or 100%.
