Treating every single flow rule as a completely independent and separate
entity negatively impacts the flow rules insertion rate. Oftentimes in an
application, many flow rules share a common structure (the same item mask
and/or action list) so they can be grouped and classified together.
This knowledge may be used as a source of optimization by a PMD/HW.

The item template defines common matching fields (the item mask) without
values. The action template holds a list of action types that will be used
together in the same rule. The specific values for items and actions will
be given only during the rule creation.

A table combines item and action templates along with shared flow rule
attributes (group ID, priority and traffic direction). This way a PMD/HW
can prepare all the resources needed for efficient flow rules creation in
the datapath. To avoid any hiccups due to memory reallocation, the maximum
number of flow rules is defined at table creation time.

The flow rule creation is done by selecting a table, an item template
and an action template (which are bound to the table), and setting unique
values for the items and actions.

+Flow templates
+~~~~~~~~~~~~~~
+
+Oftentimes in an application, many flow rules share a common structure
+(the same pattern and/or action list) so they can be grouped and classified
+together. This knowledge may be used as a source of optimization by a PMD/HW.
+The flow rule creation is done by selecting a table, an item template
+and an action template (which are bound to the table), and setting unique
+values for the items and actions. This API is not thread-safe.
+
+Item templates
+^^^^^^^^^^^^^^
+
+The item template defines a common pattern (the item mask) without values.
+The mask value is used to select a field to match on, spec/last are ignored.
+The item template may be used by multiple tables and must not be destroyed
+until all these tables are destroyed first.
+
+.. code-block:: c
+
+	struct rte_flow_item_template *
+	rte_flow_item_template_create(uint16_t port_id,
+				const struct rte_flow_item_template_attr *it_attr,
+				const struct rte_flow_item items[],
+				struct rte_flow_error *error);
+
+For example, to create an item template to match on the destination MAC:
+
+.. code-block:: c
+
+	struct rte_flow_item root_items[2] = {{0}};
+	struct rte_flow_item_eth eth_m = {0};
+	items[0].type = RTE_FLOW_ITEM_TYPE_ETH;
+	eth_m.dst.addr_bytes = "\xff\xff\xff\xff\xff\xff";
+	items[0].mask = &eth_m;
+	items[1].type = RTE_FLOW_ITEM_TYPE_END;
+
+	struct rte_flow_item_template *it =
+		rte_flow_item_template_create(port, &itr, &items, &error);
+
+The concrete value to match on will be provided at the rule creation.
+
+Action templates
+^^^^^^^^^^^^^^^^
+
+The action template holds a list of action types to be used in flow rules.
+The mask parameter allows specifying a shared constant value for every rule.
+The action template may be used by multiple tables and must not be destroyed
+until all these tables are destroyed first.
+
+.. code-block:: c
+
+	struct rte_flow_action_template *
+	rte_flow_action_template_create(uint16_t port_id,
+				const struct rte_flow_action_template_attr *at_attr,
+				const struct rte_flow_action actions[],
+				const struct rte_flow_action masks[],
+				struct rte_flow_error *error);
+
+For example, to create an action template with the same Mark ID
+but different Queue Index for every rule:
+
+.. code-block:: c
+
+	struct rte_flow_action actions[] = {
+		/* Mark ID is constant (4) for every rule, Queue Index is unique */
+		[0] = {.type = RTE_FLOW_ACTION_TYPE_MARK,
+			   .conf = &(struct rte_flow_action_mark){.id = 4}},
+		[1] = {.type = RTE_FLOW_ACTION_TYPE_QUEUE},
+		[2] = {.type = RTE_FLOW_ACTION_TYPE_END,},
+	};
+	struct rte_flow_action masks[] = {
+		/* Assign to MARK mask any non-zero value to make it constant */
+		[0] = {.type = RTE_FLOW_ACTION_TYPE_MARK,
+			   .conf = &(struct rte_flow_action_mark){.id = 1}},
+		[1] = {.type = RTE_FLOW_ACTION_TYPE_QUEUE},
+		[2] = {.type = RTE_FLOW_ACTION_TYPE_END,},
+	};
+
+	struct rte_flow_action_template *at =
+		rte_flow_action_template_create(port, &atr, &actions, &masks, &error);
+
+The concrete value for Queue Index will be provided at the rule creation.
+
+Flow table
+^^^^^^^^^^
+
+A table combines a number of item and action templates along with shared flow
+rule attributes (group ID, priority and traffic direction). This way a PMD/HW
+can prepare all the resources needed for efficient flow rules creation in
+the datapath. To avoid any hiccups due to memory reallocation, the maximum
+number of flow rules is defined at table creation time. Any flow rule
+creation beyond the maximum table size is rejected. Application may create
+another table to accommodate more rules in this case.
+
+.. code-block:: c
+
+	struct rte_flow_table *
+	rte_flow_table_create(uint16_t port_id,
+				const struct rte_flow_table_attr *table_attr,
+				struct rte_flow_item_template *item_templates[],
+				uint8_t nb_item_templates,
+				struct rte_flow_action_template *action_templates[],
+				uint8_t nb_action_templates,
+				struct rte_flow_error *error);
+
+A table can be created only after the Flow Rules management is configured
+and item and action templates are created.
+
+.. code-block:: c
+
+	rte_flow_configure(port, *port_attr, *error);
+
+	struct rte_flow_item_template *it[0] =
+		rte_flow_item_template_create(port, &itr, &items, &error);
+	struct rte_flow_action_template *at[0] =
+		rte_flow_action_template_create(port, &atr, &actions, &masks, &error);
+
+	struct rte_flow_table *table =
+		rte_flow_table_create(port, *table_attr,
+				*it, nb_item_templates,
+				*at, nb_action_templates,
+				*error);
