4467fed6f9 doc: update flow API guide for rule removal on stop
There is a discrepancy between ethdev API and flow rules guide
regarding flow rules maintenance after port stop.
librte_ethdev.h declares that flow rules will not be stored in PMD
after port stop:
>>>>> Quote start
 Please note that some configuration is not stored between calls to
 rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration
 will be retained:

 - MTU
 - flow control settings
 - receive mode configuration (promiscuous mode, all-multicast mode,
   hardware checksum mode, RSS/VMDQ settings etc.)
 - VLAN filtering configuration
 - default MAC address
 - MAC addresses supplied to MAC address array
 - flow director filtering mode (but not filtering rules)
 - NIC queue statistics mappings
<<<< Quote end

PMD cannot always correctly restore flow rules after port stop / port
start because application may alter port configuration after port stop
without PMD knowledge about undergoing changes.  Consider the
following scenario:
application configures 2 queues 0 and 1 and creates a flow rule with
'queue index 1' action. After that application stops the port and
removes queue 1.
Although PMD can implement flow rule shadow copy to be used for
restore after port start, attempt to restore flow rule from shadow
will fail in example above and PMD could not notify application about
that failure.  As the result, flow rules map in HW will differ from
what application expects.  In addition, flow rules shadow copy used
for port start restore consumes considerable amount of system memory,
especially in systems with millions of flow rules.

6e1b58fa84 usertools: add huge page setup script
This is an improved version of the setup of huge pages
bases on earlier DPDK setup.

Differences are:
   * autodetects NUMA vs non NUMA
   * allows setting different page sizes
     recent kernels support multiple sizes.
   * accepts a parameter in bytes (not pages).
   * can display current hugepage settings.

Most users will just use --setup argument but if necessary
the steps of clearing old settings and mounting/umounting
can be done individually.

1688c580e8 net/mlx5: allow unknown link speed
mlx5 PMD refuses to update link state if link speed is defined but
status is down or if link speed is undefined but status is up, even if
the ioctl() succeeded.
This prevents application to detect link up/down event, especially when
the link speed is not correctly detected.

Commit [1] allowed returning unknown link speed, so now PMD allows
the return of unknown link speed in the above case.

Due to some old kernel driver bug, link speed wasn't detected properly.

7bda955f72 doc: allow external build
Currently, when building sphinx documentation, the build will only
succeed if being run from the build system, because the conf.py script
expects DPDK_VERSION environment variable to be set, and crashes if it
is not.

However, there are certain external tools (such as sphinx documentation
preview extensions for certain IDE's) that use live preview and thus
rely on running their own sphinx commands. In these cases, it is useful
to permit building sphinx documentation without specifying the
DPDK_VERSION environment variable. The version string is the only thing
preventing manual sphinx build commands from working.

Fix the conf.py to use "None" as a version string in cases when
DPDK_VERSION environment variable is not set.

4630290af4 mbuf: move pool pointer in first half
According to the Technical Board decision
(http://mails.dpdk.org/archives/dev/2020-November/191859.html),
the mempool pointer in the mbuf struct is moved
from the second to the first half.
It may increase performance in some cases
on systems having 64-byte cache line, i.e. mbuf split in two cache lines.

Due to this change, all fields after "pool" are moved up.
Hopefully no vector data path is impacted.

Moving this field gives more space to dynfield1
while dropping the temporary dynfield0.

This is how the mbuf layout looks like (pahole-style):

4c0708ab7e app/flow-perf: configure rule batches
Currently, flow-perf measures the performance of
rule installation/deletion operations by breaking
down the entire number of operations into windows
of fixed size (i.e., 100000 operations per window).
Then, flow-perf measures the total time per window
and computes an average time across all windows.

This commit allows flow-perf users to configure
the number of rules per window instead of using
a fixed pre-compiled value. To do so, users must
pass --rules-batch=N, where N is the number of
rules per window (or batch).
For consistency reasons, flow_count variable is
now renamed to rules_count. This variable is the
total number of rules to be installed/deleted.

For example, if a user wants to measure how much
time it takes to install 1M rules in a certain NIC,
he/she can input:
--rules-count=1000000
This way flow-perf will break down 1M flow rules into
10 batches of 100k flow rules each (this is the default
batch size) and compute an average across the 10
measurements.
Now, if the user modifies the number of rules per
batch as follows:
--rules-count=1000000 --rules-batch=500000
then flow-perf will break down 1M flow rules into
2 batches of 500k flow rules each and compute the
average across the 2 measurements.

Finally, this commit also adds default variables
to the usage function instead of hardcoded values.

54c2d46b16 net/mlx5: support flow tag and packet header miniCQEs
CQE compression allows us to save the PCI bandwidth and improve
the performance by compressing several CQEs together to a miniCQE.
But the miniCQE size is only 8 bytes and this limits the ability
to successfully keep the compression session in case of various
traffic patterns.

The current miniCQE format only keeps the compression session alive
in case of uniform traffic with the Hash RSS as the only difference.
There are requests to keep the compression session in case of tagged
traffic by RTE Flow Mark Id and mixed UDP/TCP and IPv4/IPv6 traffic.
Add 2 new miniCQE formats in order to achieve the best performance
for these traffic patterns: Flow Tag and Packet Header miniCQEs.

The existing rxq_cqe_comp_en devarg is modified to specify the
desired miniCQE format. Specifying 2 selects Flow Tag format
for better compression rate in case of RTE Flow Mark traffic.
Specifying 3 selects Checksum format (existing format for MPRQ).
Specifying 4 selects L3/L4 Header format for better compression
rate in case of mixed TCP/UDP and IPv4/IPv6 traffic.

096b31fc0d net/netvsc: control use of external mbuf on Rx
When receiving packets, netvsp puts data in a buffer mapped through UIO.
Depending on packet size, netvsc may attach the buffer as an external
mbuf. This is not a problem if this mbuf is consumed in the application,
and the application can correctly read data out of an external mbuf.

However, there are two problems with data in an external mbuf.
1. Due to the limitation of the kernel UIO implementation, physical
   address of this external buffer is not exposed to the user-mode. If
   this mbuf is passed to another driver, the other driver is unable to
   map this buffer to iova.
2. Some DPDK applications are not aware of external mbuf, and may bug
   when they receive an mbuf with external buffer attached.

Introduce a driver parameter "rx_extmbuf_enable" to control if netvsc
should use external mbuf for receiving packets. The default value is 0.
(netvsc doesn't use external mbuf, it always allocates mbuf and copy
data to mbuf) A non-zero value tells netvsc to attach external buffers
to mbuf on receiving packets, thus avoid copying memory.

74a5a6663b net/netvsc: allow setting Rx and Tx copy break
The values for Rx and Tx copy break should be tunable rather
than hard coded constants.

The rx_copybreak sets the threshold where the driver uses an
external mbuf to avoid having to copy data. Setting 0 for copybreak
will cause driver to always create an external mbuf. Setting
a value greater than the MTU would prevent it from ever making
an external mbuf and always copy. The default value is 256 (bytes).

Likewise the tx_copybreak sets the threshold where the driver
aggregates multiple small packets into one request. If tx_copybreak
is 0 then each packet goes as a VMBus request (no copying).
If tx_copybreak is set larger than the MTU, then all packets smaller
than the chunk size of the VMBus send buffer will be copied; larger
packets always have to go as a single direct request. The default
value is 512 (bytes).

1a70477206 doc: mark Armv8 as supported by ena PMD
The ARMv8 platform support was tested and works fine with the ENA PMD.

It can be used on the AWS a1.* and m6g.* instances.

The ARMv8 support in ENA is at least from v19.11, where the VFIO DPDK
driver was fixed to work with 32-bit applications compiled for arm.

12b435bf8f net/iavf: support flex desc metadata extraction
Enable metadata extraction for flexible descriptors in AVF, that would
allow network function directly get metadata without additional parsing
which would reduce the CPU cost for VFs. The enabling metadata
extractions involve the metadata of VLAN/IPv4/IPv6/IPv6-FLOW/TCP/MPLS
flexible descriptors, and the VF could negotiate the capability of
the flexible descriptor with PF and correspondingly configure the
specific offload at receiving queues.
