The flow rules creation/destruction at a large scale incurs a performance
penalty and may negatively impact the packet processing when used
as part of the datapath logic. This is mainly because software/hardware
resources are allocated and prepared during the flow rule creation.
In order to optimize the insertion rate, PMD may use some hints provided
by the application at the initialization phase. The rte_flow_configure()
function allows to pre-allocate all the needed resources beforehand.
These resources can be used at a later stage without costly allocations.
Every PMD may use only the subset of hints and ignore unused ones or
fail in case the requested configuration is not supported.
The rte_flow_info_get() is available to retrieve the information about
supported pre-configurable resources. Both these functions must be called
before any other usage of the flow API engine.

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.

The default missing Tx completion timeout was set to 5 seconds.
In order to provide users with the interface to control this timeout
to adjust it with the application's watchdog, the device argument for
controlling this value was added.
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.

Originally, the ena_com memzone counter was shared by ports, which
caused the memzones to be harder to identify and could potentially
lead to race and because of that the counter had to be atomic.
This atomic counter was global variable and it couldn't work in the
multiprocess implementation.
The memzone is now being identified by the local to port memzone counter
and the port ID - both of those information can be found in the shared
data, so it can be probed easily.

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>, ...)

ENA uses AENQ for notification about various events, like LSC, keep

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

When an AF_XDP PMD is created without specifying the 'start_queue', the
default Rx queue associated with the socket will be Rx queue 0. A common
scenario encountered by users new to AF_XDP is that they create the
socket on queue 0 however their interface is configured with many more
queues. In this case, traffic might land on for example queue 18 which
means it will never reach the socket.
This commit updates the AF_XDP documentation with instructions on how to
configure the interface to ensure the traffic will land on queue 0 and
thus reach the socket successfully.

rte_gpu_mem_cpu_map() exposes a GPU memory area to the CPU.
In gpudev communication list this is useful to store the
status flag.
A communication list status flag allocated on GPU memory
and mapped for CPU visibility can be updated by CPU and polled
by a GPU workload.
The polling operation is more frequent than the CPU update operation.
Having the status flag in GPU memory reduces the GPU workload polling
latency.
If CPU mapping feature is not enabled, status flag resides in
CPU memory registered so it's visible from the GPU.
To facilitate the interaction with the status flag, this patch
provides also the set/get functions for it.
