  Template table creation API sets table flows capacity.
If application needs more flows then the table was designed for,
the following procedures must be completed:
1. Create a new template table with larger flows capacity.
2. Re-create existing flows in the new table and delete flows from
   the original table.
3. Destroy original table.

Application cannot always execute that procedure:
* Port may not have sufficient resources to allocate a new table
  while maintaining original table.
* Application may not have existing flows "recipes" to re-create
  flows in a new table.

The patch defines a new API that allows application to resize
existing template table:

* Resizable template table must be created with the
  RTE_FLOW_TABLE_SPECIALIZE_RESIZABLE_TABLE bit set.

* Application resizes existing table with the
  `rte_flow_template_table_resize()` function call.
  The table resize procedure updates the table maximal flow number
  only. Other table attributes are not affected by the table resize.
  ** The table resize procedure must not interrupt
     existing table flows operations in hardware.
  ** The table resize procedure must not alter flow handles held by
     application.

* After `rte_flow_template_table_resize()` returned, application must
  update table flow rules by calling
  `rte_flow_async_update_resized()`.
  The call reconfigures internal flow resources for the new table
  configuration.
  The flow update must not interrupt hardware flow operations.

* After table flows were updated, application must call
  `rte_flow_template_table_resize_complete()`.
  The function releases PMD resources related to the original
  table.
  Application can start new table resize after
  `rte_flow_template_table_resize_complete()` returned.

Testpmd commands:

* Create resizable template table
flow template_table <port-id> create table_id <tbl-id> resizable \
  [transfer|ingress|egres] group <group-id> \
  rules_number <initial table capacity> \
  pattern_template  <pt1> [ pattern_template <pt2> [ ... ]] \
  actions_template  <at1> [ actions_template <at2> [ ... ]]

* Resize table:
flow template_table <tbl-id> resize table_resize_id <tbl-id> \
  table_resize_rules_num <new table capacity>

* Queue a flow update:
flow queue <port-id> update_resized <tbl-id> rule <flow-id>

* Complete table resize:
flow template_table <port-id> resize_complete table <tbl-id>

This is different than previous version, I just want to confirm if this
is intentional.

Rules created *before* resize must be updated.
Rules created *after* resize not need to be updated, but if API accepts
them and just returns a quick success, this helps user and even user may
prefer to not keep track of flows as before and after resize, in a good
time user can call update for all flows.

But I am not clear why API is saying all flows (before or after) *must*
be updated?
If user is already keeping record of flows *before* resize, why not let
app to update only those flows?

Is the enforcing update of all flows done intentionally, or is it just
wording error?

I think I asked this before but perhaps missed the response,
it is possible that user missed to update all flows and called this API,
it will return -EINVAL, in this case it is not clear for user if there
is a unrecoverable error or just need to update more flows.

What do you think to send a different error for the case that there are
flows not updated, so user can action on this information.

Agree that's odd style.
DPDK prefers that way.
Please check rte_flow_driver.h::rte_flow.ops.

That API version was discussed with Thomas.
The alternative was to introduce additional function call to query
whether a flow rule needs conversion after table resize.
As the result, the application still needs to iterate on all
table flow rules.

That part remains. The application must update
flow rules created before resize.

Calling update for new rules will return success without flow update.

>this helps user and even user may
> prefer to not keep track of flows as before and after resize,

The application now does not need to differentiate table flow rules.
All table flow rules must be updated after table resize.

A different error is good.
What about EBUSY ?

True that is also odd but at least it is function pointers in a struct,
but this is regular function deceleration, why not:
```
bool
rte_flow_template_table_resizable(__rte_unused uint16_t port_id,
         const struct rte_flow_template_table_attr *tbl_attr);
```

Either it or application needs to manage it. Agree that application can
call update() on all flows is easier for app, that is why I asked for
this clarification.

But still it is different than API definition making it mandatory to
call for new flows.

What about something like, although it is a little longer:
```
Update flow for the new template table configuration after table resize.

Should be called for rules created before table resize. If called for
rules crated after table resize, API should return success, so
application is free to call this API for all flows.
```

I don't know, can be EBUSY or EAGAIN.
Or we can overload EEXIST as there are existing not updated flows.

That's very good.
I'll use it in the next patch update.

According to errno(3):
EAGAIN        Resource  temporarily  unavailable
EBUSY         Device or resource busy
EEXIST        File exists

UBUSY fits the context.

+Template API resizable table
+----------------------------
+
+Description
+~~~~~~~~~~~
+
+The resizable template table API enables applications to dynamically adjust
+capacity of template tables without disrupting the existing flow rules
+operation. The resizable template table API allows applications to optimize the
+memory usage and performance of template tables according to the traffic
+conditions and requirements.
+
+A typical use case for the resizable template table API:
+
+  #. Create a resizable table with the initial capacity.
+  #. Change the table flow rules capacity.
+  #. Update table flow objects.
+  #. Complete the table resize.
+
+A resizable table can be either in normal or resizable state.
+When application begins to resize the table, its state is changed to resizable.
+The table stays in resizable state until the application finishes resize
+procedure.
+The application can resize a table in the normal state only.
+
+The application needs to set the ``RTE_FLOW_TABLE_SPECIALIZE_RESIZABLE`` bit in
+the table attributes when creating a template table that can be resized,
+and the bit cannot be set or cleared later.
+
+The application triggers the table resize by calling
+the ``rte_flow_template_table_resize()`` function. The resize process updates
+the table configuration to fit the new flow rules capacity.
+Table resize does not change existing flow objects configuration.
+The application can create new flow rules and modify or delete existing flow
+rules while the table is resizing, but the table performance might be
+slower than usual.
+
+Flow rules that existed before table resize are fully functional after
+table resize. However, the application must update flow objects to match
+the new table configuration.
+The application calls ``rte_flow_async_update_resized()`` to update flow object
+for the new table configuration.
+All table flow rules must be updated.
+
+The application calls ``rte_flow_template_table_resize_complete()`` to return a
+table to normal state after it completed flow objects update.
