05a38d7c75 compat: provide experimental alias for matured ABI
On v20.02 some APIs matured and symbols moved from EXPERIMENTAL to
DPDK_20.0.1 block.

This had the affect of breaking the applications that were using these
APIs on v19.11. Although there is no modification of the APIs and the
action is positive and matures the APIs, the affect can be negative to
applications.

When a maintainer is promoting an API to become part of the next major
ABI version by removing the experimental tag. The maintainer may
choose to offer an alias to the experimental tag, to prevent these
breakages in future.

The following changes are made to enabling aliasing:

Updated to the ABI policy and ABI versioning documents.

Created VERSION_SYMBOL_EXPERIMENTAL helper macro.

Updated the 'check-symbols.sh' tool, which was complaining that the
symbol is in EXPERIMENTAL tag in .map file but it is not in the
.experimental section (__rte_experimental tag is missing).
Updated tool in a way it won't complain if the symbol in the
EXPERIMENTAL tag duplicated in some other block in .map file (versioned)

563ac307a4 net/mlx5: support match on GTP flags

-------------------------------------------
| bit   | 0 - 2   | 3  | 4   | 5 | 6 | 7  |
|-----------------------------------------|
| value | Version | PT | Res | E | S | PN |
-------------------------------------------

Matching is supported only for GTP flags E, S, PN.
Therefore values 0 to 7 are supported.

Mask must be set accordingly:
... gtp v_pt_rsv_flags is 1 v_pt_rsv_flags mask 0x07 ...

6b30428820 doc: refine ethernet and VLAN flow rule items
Specified pattern may be translated in different manner.
For example the pattern "eth / ipv4" can be translated to match
untagged packets only, since the pattern doesn't specify a VLAN item.
It can also be translated to match both tagged and untagged packets,
for the same reason.
This patch updates the rte_flow documentation to clearly specify the
required pattern to use.
For example:
To match tagged ipv4 packets, the pattern "eth / vlan / ipv4 / end"
should be used.
To match untagged ipv4 packets, the pattern "eth / ipv4 / end"
should be used.
To match all IPV4 packets, both tagged and untagged, need to apply
two rules with the patterns above.
To match both tagged and untagged packets of any type, the pattern
"eth / end" should be used.

9eb974221f app/testpmd: fix statistics after reset
Currently, when running start/clear stats&xstats/stop command many times
based on testpmd application, there are incorrect forward Rx/Tx-packets
stats as below:
---------------------- Forward statistics for port 0  --------------
RX-packets: 18446744073709544808 RX-dropped: 0                <snip>
TX-packets: 18446744073709536616 TX-dropped: 0                <snip>
--------------------------------------------------------------------

The root cause as below:
1. The struct rte_port of testpmd.h has a member variable "struct
   rte_eth_stats stats" to store the last port statistics.
2. When running start command, it execute cmd_start_parsed ->
   start_packet_forwarding -> fwd_stats_reset, which call
   rte_eth_stats_get API function to save current port statistics.
3. When running stop command, it execute fwd_stats_display, which call
   rte_eth_stats_get to get current port statistics, and then minus last
   port statistics.
4. If we run clear stats or xstats after start command, then run stop,
   it may display above incorrect stats because the current
   Rx/Tx-packets is lower than the last saved RX/TX-packets(uint64_t
   overflow).

This patch fixes it by clearing last port statistics when executing
"clear stats/xstats" command.

fa2d01c87d net/mlx5: support flow aging
Currently, there is no flow aging check and age-out event callback
mechanism for mlx5 driver, this patch implements it. It's included:
- Splitting the current counter container to aged or no-aged container
  since reducing memory consumption. Aged container will allocate extra
  memory to save the aging parameter from user configuration.
- Aging check and age-out event callback mechanism based on current
  counter. When a flow be checked aged-out, RTE_ETH_EVENT_FLOW_AGED
  event will be triggered to applications.
- Implement the new API: rte_flow_get_aged_flows, applications can use
  this API to get aged flows.

44bf3c796b ethdev: support flow aging
One of the reasons to destroy a flow is the fact that no packet matches
the flow for "timeout" time.
For example, when TCP\UDP sessions are suddenly closed.

Currently, there is not any DPDK mechanism for flow aging and the
applications use their own ways to detect and destroy aged-out flows.

The flow aging implementation need include:
- A new rte_flow action: RTE_FLOW_ACTION_TYPE_AGE to set the timeout and
  the application flow context for each flow.
- A new ethdev event: RTE_ETH_EVENT_FLOW_AGED for the driver to report
  that there are new aged-out flows.
- A new rte_flow API: rte_flow_get_aged_flows to get the aged-out flows
  contexts from the port.
- Support input flow aging command line in Testpmd.

The new event type addition in the enum is flagged as an ABI breakage,
so an ignore rule is added for these reasons:
- It is not changing value of existing types (except MAX)
- The new value is not used by existing API if the event is not
  registered
In general, it is safe adding new ethdev event types at the end of the
enum, because of event callback registration mechanism.

02a95625fe net/bnxt: add flow stats in extended stats
This patch allows to display flow stats in extended stats.
To do this, DMA-able memory is registered with the FW during device
initialization. Then the driver uses an alarm thread to query the
per flow stats using the HWRM_CFA_COUNTER_QSTATS HWRM command at
regular intervals and stores it locally which will be displayed
when the application queries the xstats.
The DMA-able memory is unregistered during driver cleanup.
This functionality can be enabled using the flow-xstat devarg and
will be disabled by default. The intention behind this is to allow
stats to be displayed for all the flows in one shot instead of
querying one at a time.

fe9a344c5b doc: add notes on ENA usage on metal instances
As AWS metal instances are supporting IOMMU, the usage of igb_uio or
vfio-pci can lead to a problems (when to use which module), especially
that the vfio-pci isn't supporting SMMU on arm64.

To clear up the problem of using those modules in various setup
conditions (with or without IOMMU) on metal instances, more detailed
explanation was added.

83fd97b206 net/ena: reuse zero length Rx descriptor
Some ENA devices can pass to the driver descriptor with length 0. To
avoid extra allocation, the descriptor can be reused by simply putting
it back to the device.

33dde075fc net/ena: disable meta caching
In the LLQ (Low-latency queue) mode, the device can indicate that meta
data descriptor caching is disabled. In that case the driver should send
valid meta descriptor on every Tx packet.

e1e73e3229 net/ena: add Tx drops statistic
ENA device can report in the AENQ handler amount of Tx packets that were
dropped and not sent.

This statistic is showing global value for the device and because
rte_eth_stats is missing field that could indicate this value (it
isn't the Tx error), it is being presented as a extended statistic.

As the current design of extended statistics prevents tx_drops from
being an atomic variable and both tx_drops and rx_drops are only updated
from the AENQ handler, both were set as non-atomic for the alignment.

8a7a73f26c net/ena: support large LLQ headers
Default LLQ (Low-latency queue) maximum header size is 96 bytes and can
be too small for some types of packets - like IPv6 packets with multiple
extension. This can be fixed, by using large LLQ headers.

If the device supports larger LLQ headers, the user can activate them by
using device argument 'large_llq_hdr' with value '1'.

If the device isn't supporting this feature, the default value (96B)
will be used.
