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 v6 00/11] Bunch of flow API-related fixes"
http://dpdk.org/ml/archives/dev/2018-April/098035.html
v5 changes:
- Fixed errors reported by GCC and Clang in patch 05/16 ("ethdev: alter
behavior of flow API actions").
- Rebased series once again.
v4 changes:
- No change besides new acked-by lines, rebased series to address conflicts.
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.
