SW Steering: Support pattern/args modify_header actions
The following patch series adds support for a new pattern/arguments type
of modify_header actions.
Starting with ConnectX-6 DX, we use a new design of modify_header FW object.
The current modify_header object allows for having only limited number of
these FW objects, which means that we are limited in the number of offloaded
flows that require modify_header action.
The new approach comprises of two types of objects: pattern and argument.
Pattern holds header modification templates, later used with corresponding
argument object to create complete header modification actions.
The pattern indicates which headers are modified, while the arguments
provide the specific values.
Therefore a single pattern can be used with different arguments in different
flows, enabling offloading of large number of modify_header flows.
- Patch 1, 2: Add ICM pool for modify-header-pattern objects and implement
patterns cache, allowing patterns reuse for different flows
- Patch 3: Allow for chunk allocation separately for STEv0 and STEv1
- Patch 4: Read related device capabilities
- Patch 5: Add create/destroy functions for the new general object type
- Patch 6: Add support for writing modify header argument to ICM
- Patch 7, 8: Some required fixes to support pattern/arg - separate read
buffer from the write buffer and fix QP continuous allocation
- Patch 9: Add pool for modify header arg objects
- Patch 10, 11, 12: Implement MODIFY_HEADER and TNL_L3_TO_L2 actions with
the new patterns/args design
- Patch 13: Optimization - set modify header action of size 1 directly on
the STE instead of separate pattern/args combination
- Patch 14: Adjust debug dump for patterns/args
- Patch 15: Enable patterns and arguments for supporting devices
