This patch adds shared action support to testpmd CLI.
All shared actions created via testpmd CLI assigned ID for further
reference in other CLI commands. Shared action ID supplied as CLI
argument or assigned by testpmd is similar to flow ID & limited to
scope of testpdm CLI.
Create shared action syntax:
flow shared_action {port_id} create [action_id {shared_action_id}]
[ingress] [egress] action {action} / end
Create shared action examples:
flow shared_action 0 create action_id 100 \
ingress action rss queues 1 2 end / end
This creates shared rss action with id 100 on port 0.
flow shared_action 0 create action_id \
ingress action rss queues 0 1 end / end
This creates shared rss action with id assigned by testpmd
on port 0.
Update shared action syntax:
flow shared_action {port_id} update {shared_action_id}
action {action} / end
Update shared action example:
flow shared_action 0 update 100 \
action rss queues 0 3 end / end
This updates shared rss action having id 100 on port 0
with rss to queues 0 3 (in create example rss queues were
1 & 2).
Destroy shared action syntax:
flow shared_action {port_id} destroy action_id {shared_action_id} [...]
Destroy shared action example:
flow shared_action 0 destroy action_id 100 action_id 101
This destroys shared actions having id 100 & 101
Query shared action syntax:
flow shared_action {port} query {shared_action_id}
Query shared action example:
flow shared_action 0 query 100
This queries shared actions having id 100
Use shared action as flow action syntax:
flow create {port_id} ... / end actions [action / [...]]
shared {action_id} / [action / [...]] end
Use shared action as flow action example:
flow create 0 ingress pattern ... / end \
actions shared 100 / end
This creates flow rule where rss action is shared rss action
having id 100.
All shared action CLIs report status of the command.
Shared action query CLI output depends on action type.

+Updating shared actions
+~~~~~~~~~~~~~~~~~~~~~~~
+``flow shared_action {port_id} update`` updates configuration of the shared
+action from its shared action ID (as returned by
+``flow shared_action {port_id} create``). It is bound to
+``rte_flow_shared_action_update()``::
+
+ flow shared_action {port_id} update {shared_action_id}
+ action {action} / end
+
+If successful, it will show::
+
+ Shared action #[...] updated
+
+Otherwise, it will complain either that shared action not found or that some
+error occurred::
+
+ Failed to find shared action #[...] on port [...]
+
+::
+
+ Caught error type [...] ([...]): [...]
+
+Update shared rss action having id 100 on port 0 with rss to queues 0 and 3
+(in create example above rss queues were 1 and 2)::
+
+ testpmd> flow shared_action 0 update 100 action rss queues 0 3 end / end
+
+Destroying shared actions
+~~~~~~~~~~~~~~~~~~~~~~~~~
+``flow shared_action {port_id} update`` destroys one or more shared actions
+from their shared action IDs (as returned by
+``flow shared_action {port_id} create``). It is bound to
+``rte_flow_shared_action_destroy()``::
+
+ flow shared_action {port_id} destroy action_id {shared_action_id} [...]
+
+If successful, it will show::
+
+ Shared action #[...] destroyed
+
+It does not report anything for shared action IDs that do not exist.
+The usual error message is shown when a shared action cannot be destroyed::
+
+ Caught error type [...] ([...]): [...]
+
+Destroy shared actions having id 100 & 101::
+
+ testpmd> flow shared_action 0 destroy action_id 100 action_id 101
+
+Query shared actions
+~~~~~~~~~~~~~~~~~~~~
+``flow shared_action {port_id} query`` queries the shared action from its
+shared action ID (as returned by ``flow shared_action {port_id} create``).
+It is bound to ``rte_flow_shared_action_query()``::
+
+ flow shared_action {port_id} query {shared_action_id}
+
+Currently only rss shared action supported. If successful, it will show::
+
+ Shared RSS action:
+ refs:[...]
+
+Otherwise, it will complain either that shared action not found or that some
+error occurred::
+
+ Failed to find shared action #[...] on port [...]
+

+
+Query shared action having id 100::
