295968d174 ethdev: add namespace
Add 'RTE_ETH' namespace to all enums & macros in a backward compatible
way. The macros for backward compatibility can be removed in next LTS.
Also updated some struct names to have 'rte_eth' prefix.

All internal components switched to using new names.

Syntax fixed on lines that this patch touches.

a89f6433aa net/mlx5: set Tx queue affinity in round-robin
Previously, we set txq affinity to 0 and let firmware
to perform round-robin when bonding. Firmware uses a
global counter to assign txq affinity to different
physical ports accord to remainder after division.

There are three dis-advantages:
1. The global counter is shared between kernel and dpdk.
2. After restarting pmd or port, the previous counter value
is reused, so the new affinity is unpredictable.
3. There is no way to get what affinity is set by firmware.

In this update, we will create several TISs up to the
number of bonding ports and bind each TIS to one PF port.

For each port, it will start to pick up TIS using its port
index. Upper layer application can quickly calculate each txq's
affinity without querying.

At DPDK layer, when creating txq with 2 bonding ports, the
affinity is set like:
port 0: 1-->2-->1-->2
port 1: 2-->1-->2-->1
port 2: 1-->2-->1-->2

Note: Only applicable to DevX api.
This affinity subjects to HW hash.

ea823b2c51 net/mlx5: close tools socket with last device
MLX5 PMD exposes a socket for external tools to dump port state.
Socket events are listened using an interrupt source of EXT type.
The socket was closed and the interrupt callback was unregistered
at program exit, which is incorrect because DPDK could be already
shut down at this point. Move actions performed at program exit
to the moment the last MLX5 port is closed. The socket will be opened
again if later a new MLX5 device is plugged in and probed.
Also fix comments that were decisively talking
about secondary processes instead of external tools.

fec28ca0e3 net/mlx5: support mempool registration
When the first port in a given protection domain (PD) starts,
install a mempool event callback for this PD and register all existing
memory regions (MR) for it. When the last port in a PD closes,
remove the callback and unregister all mempools for this PD.
This behavior can be switched off with a new devarg: mr_mempool_reg_en.

On TX slow path, i.e. when an MR key for the address of the buffer
to send is not in the local cache, first try to retrieve it from
the database of registered mempools. Supported are direct and indirect
mbufs, as well as externally-attached ones from MLX5 MPRQ feature.
Lookup in the database of non-mempool memory is used as the last resort.

RX mempools are registered regardless of the devarg value.
On RX data path only the local cache and the mempool database is used.
If implicit mempool registration is disabled, these mempools
are unregistered at port stop, releasing the MRs.

a6b57ff487 net/mlx5: fix flow tables double release
In the function mlx5_alloc_shared_dr(), there are various reasons
to result in a failure and error clean up process. While in the
caller of mlx5_dev_spawn(), once there is a error occurring after
the mlx5_alloc_shared_dr(), the mlx5_os_free_shared_dr() is called
to release all the resources.

To prevent a double release, the pointers of the resources should
be checked before the releasing and set to NULL after done.

In the mlx5_free_table_hash_list(), after the releasing, the pointer
was missed to set to NULL and a double release may cause a crash.

By setting the tables pointer to NULL as done for other resources,
the double release and crash could be solved.

The root device parameter was specified as NULL, and it caused

4f3d8d0ea3 net/mlx5: move header modify allocator to ipool
Modify header actions are allocated by mlx5_malloc which has a big
overhead of memory and allocation time.

One of the action types under the modify header object is SET_TAG,

The SET_TAG action is commonly not reused by the flows and each flow has
its own value.

Hence, the mlx5_malloc becomes a bottleneck in flow insertion rate in
the common cases of SET_TAG.

Use ipool allocator for SET_TAG action.

Ipool allocator has less overhead of memory and insertion rate and has
better synchronization mechanism in multithread cases.

Different ipool is created for each optional size of modify header
handler.

eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +

ee9e5fad03 net/mlx5: initialize connection tracking management
The definitions of ASO connection tracking objects management
structures are added.

Considering performance, the bulk allocation of ASO CT objects
should be used. The maximal value per bulk and the granularity could
be fetched from HCA capabilities 2. Right now, a fixed number of 64
is used for each bulk for a better management purpose.

The ASO QP for CT is initialized, the SQ will be used for both
modify and query command.

a8f0df6bf9 net/mlx5: support power monitoring
Support the PMD power management API in MLX5 driver.
The monitor policy of this API puts a CPU core to sleep until
a data in some monitored memory address is changed by the NIC.
Implement the get_monitor_addr function to return an address
of a CQE owner bit to monitor the arrival of a new packet.

447d4d797d net/mlx5: fix flow age event triggering
A FLOW_AGE event should be invoked when a new aged-out flow is detected
by the PMD after the last user get-aged query calling.
The PMD manages 2 flags for this information and check them in order to
decide if an event should be invoked:
MLX5_AGE_EVENT_NEW - a new aged-out flow was detected. after the last
check.
MLX5_AGE_TRIGGER - get-aged query was called after the last aged-out
flow.
The 2 flags were unset after the event invoking.

When the user calls get-aged query from the event callback, the TRIGGER
flag was set inside the user callback and unset directly after the
callback what may stop the event invoking forever.

Unset the TRIGGER flag before the event invoking in order to allow set
it by the user callback.

afb4aa4f12 net/mlx5: support meter policy operations
MLX5 PMD checks the validation of actions in policy while add
a new meter policy, if pass the validation, allocates the new
policy object from the meter policy indexed memory pool.

It is common to use the same policy for multiple meters.
MLX5 PMD supports two types of policy: termination policy and
no-termination policy.

Implement the next policy operations:
validate:
The driver doesn't support to configure actions in the flow
after the meter action except one case when the meter policy
is configured to do nothing in GREEN\YELLOW and only DROP action
in RED, this special policy is called non-terminated policy
and is handed as a singleton object internally.

For all the terminated policies, the next actions are supported:
GREEN - QUEUE, RSS, PORT_ID, JUMP, DROP, MARK and SET_TAG.
YELLOW - not supported at all -> must be empty.
RED - must include DROP action.

Hence, in ingress case, for example,
QUEUE\RSS\JUMP must be configured as last action for GREEN color.

All the above limitations will be validated.

create:
Validate the policy configuration.
Prepare the related tables and actions.

destroy:
Release the created policy resources.

2d2cef5d4f net/mlx5: allow multiple flow tables on same level
The driver devices support creation of multiple flow tables.
Jump action can be used in order to move the packet steering
to different flow table.
Table 0 is always the root table for packet steering.

Jumping between tables may cause endless loops in steering mechanism,
that's why each table has level attribute,
the driver sub-system may not allow jumping to table with
equal or lower level than the current table.

Currently, in the driver, the table ID and level are always identical.

Allow multiple flow table creation with the same level attribute.

This patch adds the table id in flow table data entry, while
allocates the flow table, if the table level is same but the
different table id, the new table will be allocated with new
table object id. It supports 4M multiple flow tables on the
same level.
