Now that there is VCAP support, it is possible to add entries in the VCAP to trap frames to the CPU and the CPU will forward these frames. The first part of the patch series, extends the VCAP support to be able to modify and get the rule, while the last patch uses the VCAP to trap the ptp frames. v2->v3: - rebase on net-next as it didn't apply anymore v1->v2: - use PTP_EV_PORT and PTP_GEN_PORT instead of hardcoding the number - small alignment adjustments Horatiu Vultur (4): net: microchip: vcap: Add vcap_get_rule net: microchip: vcap: Add vcap_mod_rule net: microchip: vcap: Add vcap_rule_get_key_u32 net: lan966x: Add ptp trap rules .../ethernet/microchip/lan966x/lan966x_main.c | 19 +- .../ethernet/microchip/lan966x/lan966x_main.h | 14 + .../ethernet/microchip/lan966x/lan966x_ptp.c | 236 ++++- .../microchip/lan966x/lan966x_tc_flower.c | 8 - .../microchip/lan966x/lan966x_vcap_impl.c | 11 +- .../net/ethernet/microchip/vcap/vcap_api.c | 824 ++++++++++++++++++ .../ethernet/microchip/vcap/vcap_api_client.h | 8 + .../microchip/vcap/vcap_api_debugfs.c | 498 ++--------- .../microchip/vcap/vcap_api_private.h | 14 + 9 files changed, 1171 insertions(+), 461 deletions(-) -- 2.38.0
