Commit Message

Qi Zhang Sept. 11, 2023, 4:51 p.m. UTC 
  This marks the initial phase of refactoring the ice rte_flow
implementation.

The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.

To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-- ``Generic Flow Pipeline Mode Support`` (default ``0``)
-
-  In pipeline mode, a flow can be set at one specific stage by setting parameter
-  ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
-  priority 0 located at the first pipeline stage which typically be used as a firewall
-  to drop the packet on a blocklist(we called it permission stage). At this stage,
-  flow rules are created for the device's exact match engine: switch. Flows with priority
-  !0 located at the second stage, typically packets are classified here and be steered to
-  specific queue or queue group (we called it distribution stage), At this stage, flow
-  rules are created for device's flow director engine.
-  For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
-  rule or a switch rule depends on its pattern/action and the resource allocation situation,
-  all flows are virtually at the same pipeline stage.
-  By default, generic flow API is enabled in none-pipeline mode, user can choose to
-  use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
-  for example::
-
-    -a 80:00.0,pipeline-mode-support=1
-
 - ``Default MAC Disable`` (default ``0``)
 
   Disable the default MAC make the device drop all packets by default,
