When the TC tool add a flower filter the VCAP rule corresponding to this filter will be disabled (kept in memory) until a TC matchall filter creates a link from chain 0 to the chain (lookup) where the flower filter was added. When the flower filter is enabled it will be written to the appropriate VCAP lookup and become active in HW. Likewise the flower filter will be disabled if there is no link from chain 0 to the chain of the filter (lookup), and when that happens the corresponding VCAP rule will be read from the VCAP instance and stored in memory until it is deleted or enabled again. Version History: ================ v2 Adding a missing goto exit in vcap_add_rule (Dan Carpenter). Added missing checks for error returns in vcap_enable_rule. v1 Initial version Steen Hegelund (8): net: microchip: vcap api: Erase VCAP cache before encoding rule net: microchip: sparx5: Reset VCAP counter for new rules net: microchip: vcap api: Always enable VCAP lookups net: microchip: vcap api: Convert multi-word keys/actions when encoding net: microchip: vcap api: Use src and dst chain id to chain VCAP lookups net: microchip: vcap api: Check chains when adding a tc flower filter net: microchip: vcap api: Add a storage state to a VCAP rule net: microchip: vcap api: Enable/Disable rules via chains in VCAP HW .../ethernet/microchip/lan966x/lan966x_goto.c | 10 +- .../ethernet/microchip/lan966x/lan966x_main.h | 3 +- .../microchip/lan966x/lan966x_tc_flower.c | 30 +- .../microchip/lan966x/lan966x_tc_matchall.c | 16 +- .../microchip/lan966x/lan966x_vcap_impl.c | 24 +- .../microchip/sparx5/sparx5_tc_flower.c | 28 +- .../microchip/sparx5/sparx5_tc_matchall.c | 16 +- .../microchip/sparx5/sparx5_vcap_debugfs.c | 2 +- .../microchip/sparx5/sparx5_vcap_impl.c | 29 +- .../net/ethernet/microchip/vcap/vcap_api.c | 762 +++++++++++++----- .../net/ethernet/microchip/vcap/vcap_api.h | 5 - .../ethernet/microchip/vcap/vcap_api_client.h | 8 +- .../microchip/vcap/vcap_api_debugfs.c | 57 +- .../microchip/vcap/vcap_api_debugfs_kunit.c | 10 +- .../ethernet/microchip/vcap/vcap_api_kunit.c | 32 +- .../microchip/vcap/vcap_api_private.h | 12 +- 16 files changed, 694 insertions(+), 350 deletions(-) -- 2.39.0
