ea695031a7 net/cnxk: fix inline IPsec security error handling
Use raw mbuf free on inline security error to simulate
HW NPA free instead of doing rte_pktmbuf_free(). This
is needed as the callback will not be called from
DPDK lcore.

90b361368c common/cnxk: remove tracking of mark actions
Removed roc NPC APIs which tracks addition and deletion of
mark actions. It was earlier needed to track number of mark
actions added as part of flow rules. If mark actions count

a6b9d5a538 common/mlx5: update doorbell mapping parameter name
The "tx_db_nc" devarg forces doorbell register mapping to non-cached
region eliminating the extra write memory barrier. This argument was
used in creating the UAR for Tx and thus affected its performance.

Recently [1] its use has been extended to all UAR creation in all mlx5
drivers, and now its name is no longer so accurate.

This patch changes its name to "sq_db_nc" to suit any send queue that
uses it. The old name will still work for backward compatibility.

38eb5c9f35 net/mlx5: fix E-Switch manager vport ID
One of the E-Switch vports plays the special role - it is assigned as
"E-Switch manager" and has some special exclusive rights and duties - it
maintains all the representors, manages FDB domain flows, etc. By
default, the E-Switch vport index was supposed to be zero on standalone
NICs (regular ConnectX) and 0xFFFE SmartNIC (BlueField), but that was
not always correct - this index can be assigned with any value by
kernel/hypervisor.

Currently the E-Switch manager vport id is supposed to be default - 0
for standalone NICs, and 0xFFFE for the SmartNICs, and is deduced from
the device PCI id.

To handle this and do not suggest any default values, can use DevX API
to query E-Switch manager vport ID directly from the firmware during
initialization, and use that value by default. If the new method is not
provided (legacy firmware), fallback to use the PCI id approach.

f685878a56 net/mlx5: optimize Rx queue creation
Recently shared RxQ has been introduced. All shared Rx queues with same
group and queue ID share the same rxq_ctrl, but each one has
mlx5_rxq_priv structure.
The mlx5_rx_queue_setup generates a new rxq_priv structure, and looks
for a rxq_ctrl structure to refer to. If there is already a compatible
rxq_ctrl structure it refers it, otherwise it calls the mlx5_rxq_new
function that generates a new one.

This patch makes mlx5_rxq_new function "standalone", it generates a
rxq_ctrl structure regardless to specific rxq_priv structure. All
operations on the rxq_ctrl structure that depend on the new rxq_priv
structure are performed in the mlx5_rx_queue_setup function, at the same
place for either a new rxq_ctrl structure or an existing rxq_ctrl
structure.

05b54bf089 common/mlx5: fix queue pair ack timeout configuration
VDPA driver creates two QPs(1 queue pair include 1 send queue
and 1 receive queue) per virtio queue to get traffic events
from NIC to SW.
Two QPs(called FW QP and SW QP) are created as loopback QP
and FW QP'SQ is connected to SW QP'RQ internally.

When packet receive or send out, HW will send WQE by FW QP'SQ,
then SW will get CQE from the CQ of SW QP.

With large scale and heavy traffic, the SQ's request may fail
to get ACK from RQ HW, because HW is busy.
SQ will retry the request with qpc.retry_count times and each time
wait for 4.096 uS *2^(ack_timeout) for the response. If still can’t
get RQ’s HW response, SQ will go to an error state.

16 is experienced value. It should not be too high or too low.
Too high will make QP waits too long in case it’s packet drop.
Too low will cause QP to go to an error state(retry-exceeded) easily.

022fb61b62 net/ena: fix meta descriptor DF flag setup
Whenever Tx checksum offload is being used, the meta descriptor content
is taken into consideration. Setting DF field properly in the meta
descriptor may have huge impact on the performance both for the IPv4 and
IPv6 packets.

The requirements for the df field are as below:
* No offload used - value doesn't matter
* IPv4 - 0 or 1, depending on the DF flag in the IPv4 header
* IPv6 - 1

Setting DF to 0 causes the packet to enter the slow-path in the HW and
as a result can noticeable impact the performance.

Moreover, as 'true' may not always be mapped to 1 depending on it's
definition for the given platform/compiler, for safety DF field is being
set explicitly to 1.

The default missing Tx completion timeout was set to 5 seconds.
In order to provide users with the interface to control this timeout

The parameter is called 'miss_txc_to' and can be modified using the
devargs interface:

  ./app -a <bdf>,miss_txc_to=UINT_NUMBER

This parameter accepts values from 0 to 60 and indicates number of
seconds after which the Tx packet will be considered as missing.

HW hints for the Tx completions timeout were removed to do not overwrite
parameter from the user. Also specifying default Tx completion timeout
value was moved from the configuration to init phase in order to
simplify default value assignment.

Since statistic gathering is now proxied safely to primary process, it
can be enabled in secondary processes.

e3595539e0 net/ena: proxy AQ calls to primary process
Due to how the ena_com compatibility layer is written, all AQ commands
triggering functions use stack to save results of AQ and then copy them
to user given function.
Therefore to keep the compatibility layer common, introduce ENA_PROXY
macro. It either calls the wrapped function directly (in primary
process) or proxies it to the primary via DPDK IPC mechanism. Since all
proxied calls are taken under a lock share the result data through
shared memory (in struct ena_adapter) to work around 256B IPC parameter
size limit.

New proxy calls can be added by
1. Adding a new message type at the end of enum ena_mp_req
2. Adding new message arguments to the struct ena_mp_body if needed
3. Defining proxy request descriptor with ENA_PROXY_DESC. Its arguments
   include handlers for request preparation and response processing.
   Any of those may be empty (aside of marking arguments as used).
4. Adding request handling logic to ena_mp_primary_handle()
5. Replacing proxied function calls with ENA_PROXY(adapter, <func>, ...)

b2c1fe38ad net/ena/base: use optimized memcpy version also on Arm
As the default behavior for arm64 is to alias rte_memcpy as memcpy, ENA
cannot redefine memcpy as rte_memcpy as it would cause nested
declaration.

To make it possible to use optimized memcpy in the ena_com layer on Arm,
the driver now redefines memcpy when it is beneficial:
  * For arm64 only when the flag RTE_ARCH_ARM64_MEMCPY was defined
  * For arm only when the flag RTE_ARCH_ARM_NEON_MEMCPY was defined

67216c31e4 net/ena: perform Tx cleanup before sending packets
To increase likelihood that current burst will fit in the HW rings,
perform Tx cleanup before pushing packets to the HW. It may increase
latency a bit for sparse bursts, but the Tx flow now should be more
smooth.

It's also common order in the Tx burst function for other PMDs.

e2174a5446 net/ena: skip timer if reset is triggered
Some user applications may not support PMD reset handling. If they will
support timer service it could cause a situation, when information
about the reset trigger is being showed every time the timer service is
being called.

Timer service is now being skipped if the reset was already triggered.

b9b05d6f86 net/ena: make link status change interrupt configurable
ENA uses AENQ for notification about various events, like LSC, keep
alive etc. By default it was enabling all AENQ that were supported by
both the driver and the device. As a result the LSC was always processed
even if the application turned it off explicitly.

As the DPDK provides application with the possibility to configure the
LSC, ENA should respect that. AENQ groups are now being updated upon
configure step, thus LSC can be activated or disabled between ENA PMD
reconfigurations. Moreover, the LSC capability for the device is being
determined dynamically.

* Split 'bad_csum' Rx statistic into 'l3_csum_bad' and 'l4_csum_bad' to

* Add l4_csum_good statistic, which shows how many times L4 Rx checksum
  was properly offloaded.
