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: Version History: ================ v3 Add some more details to the explanation in the commit message about support for MAC_ETYPE keysets and "protocol all" as well as the classified VLAN information. This is done to help testing the feature. No implementation changes in this version. v2 Split one of the KUNIT tests into 3 tests to fix a kernel robot build warning. v1 Initial version 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 | 447 ++++++++++++++++++ 5 files changed, 1256 insertions(+), 33 deletions(-)
