It builds on top of the initial IS2 VCAP support found in this series: https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/ Overview: ========= The added flower filter key (dissector) support is this: - ipv4_addr (sip and dip) - ipv6_addr (sip and dip) - control (IPv4 fragments) - portnum (tcp and udp port numbers) - basic (L3 and L4 protocol) - vlan (outer vlan tag info) - tcp (tcp flags) - ip (tos field) The IS2 VCAP supports classified VLAN information which amounts to the outer VLAN info in case of multiple tags. Functionality: ============== Before frames can match IS2 VCAP rules with e.g an IPv4 source address, the IS2 VCAPs keyset configuration must include keyset that contains a IPv4 source address and this must be configured for the lookup/port/traffic-type that you want to match on. The Sparx5 IS2 VCAP has the following traffic types: - Non-Ethernet frames - IPv4 Unicast frames - IPv4 Multicast frames - IPv6 Unicast frames - IPv6 Multicast frames - ARP frames So to cover IPv4 traffic the two IPv4 categories must be configured with a keyset that contains IPv4 address information such as the VCAP_KFS_IP4_TCP_UDP keyset. The IPv4 and IPv6 traffic types are configured with useful default keysets, in later series we will use the tc template functionality when we want to change these defaults. Delivery: ========= This is current plan for delivering the full VCAP feature set of Sparx5: - support for TC protocol all - debugfs support for inspecting rules - TC flower filter statistics using VCAP counters - Sparx5 IS0 VCAP support and more TC keys and actions to support this - add TC policer and drop action support (depends on the Sparx5 QoS support upstreamed separately) - Sparx5 ES0 VCAP support and more TC actions to support this - TC flower template support - TC matchall filter support for mirroring and policing ports - TC flower filter mirror action support - Sparx5 ES2 VCAP support Steen Hegelund (5): net: microchip: sparx5: Differentiate IPv4 and IPv6 traffic in keyset config net: microchip: sparx5: Adding more tc flower keys for the IS2 VCAP net: microchip: sparx5: Match keys in configured port keysets net: microchip: sparx5: Let VCAP API validate added key- and actionfields net: microchip: sparx5: Adding KUNIT tests of key/action values in VCAP API .../microchip/sparx5/sparx5_tc_flower.c | 410 +++++++++++++++++- .../microchip/sparx5/sparx5_vcap_impl.c | 168 ++++++- .../net/ethernet/microchip/vcap/vcap_api.c | 251 ++++++++++- .../ethernet/microchip/vcap/vcap_api_client.h | 13 + .../ethernet/microchip/vcap/vcap_api_kunit.c | 406 +++++++++++++++++ 5 files changed, 1215 insertions(+), 33 deletions(-)
