Subject: [dpdk-dev] [PATCH v3 00/16] Flow API overhaul for switch offloads
Date: Tue, 10 Apr 2018 18:36:38 +0200	[thread overview]
Message-ID: <20180410162022.9101-1-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <20180406131736.19145-1-adrien.mazarguil@6wind.com>

As summarized in a prior RFC [1], the flow API (rte_flow) was chosen as a
means to manage switch offloads supported by many devices (usually going by
names such as E-Switch or vSwitch) through user-specified flow rules.

Combined with the need to support encap/decap actions, this requires a
change in the way flow actions are processed (in order and possibly
repeated) which modifies the behavior of some of the existing actions, thus
warranting a major ABI breakage.

Given this ABI breakage is also required by other work submitted for the
current release [2][3], this series addresses various longstanding issues
with the flow API and makes minor improvements in preparation for upcoming
features.

Changes summary:

- Additional error types.
- Clearer documentation.
- Improved C++ compatibility.
- Exhaustive RSS action.
- Consistent behavior of VLAN pattern item.
- New "transfer" attribute bringing consistency to VF/PF pattern items.
- Confusing "PORT" pattern item renamed "PHY_PORT", with new action
  counterpart.
- New "PORT_ID" pattern item and action to be used with port representors.

This series piggybacks on the major ABI update introduced by a prior
commit [4] for DPDK 18.05 and depends on several fixes [5] which must be
applied first.

[1] "[RFC] Switch device offload with DPDK"
    http://dpdk.org/ml/archives/dev/2018-March/092513.html

[2] commit 676b605182a5 ("doc: announce ethdev API change for RSS
    configuration")

[3] "[PATCH v1 00/21] MLX5 tunnel Rx offloading"
    http://dpdk.org/ml/archives/dev/2018-March/092264.html

[4] commit 653e038efc9b ("ethdev: remove versioning of filter control
    function")

[5] "[PATCH v4 00/11] Bunch of flow API-related fixes"
    http://dpdk.org/ml/archives/dev/2018-April/096509.html

v3 changes:

- Rebased series, fixed latest conflicts.
- Addressed Andrew's comments, see affected patches for details:
  - Empty RSS types in flow rule means PMD-specific RSS instead of no RSS.
  - RSS hash function now explicitly compared against
    RTE_ETH_HASH_FUNCTION_DEFAULT instead of 0 in all PMDs.
  - sfc PMD updated to also accept Toeplitz.
  - Implicit VLAN TPID matching now removed from all PMDs.
  - Default mask upate for VLAN TCI now split as separate patch #11.
  - Ingress/egress definition clarified in patch #12.

v2 changes:

- Squashed "ethdev: update ABI for flow API functions" in subsequent
  patches.
- Emphasized ABI impact in relevant commit logs.
- Modified documentation in "ethdev: alter behavior of flow API actions" to
  describe how terminating flow rules without any action of the fate kind
  result in undefined behavior instead of dropping traffic.
- Fixed other minor documentation formatting issues.
- Modified "ethdev: refine TPID handling in flow API" as follows:
  - Using standard macro definitions for VLAN, QinQ and E-Tag EtherTypes.
  - Fixed endian conversion in sfc.
  - Replaced a condition in VLAN pattern item processing with an assertion
    check for i40e.
