From: Jiri Pirko <j...@mellanox.com> This patchset introduces a control action dedicated to indicate to trap the matched packet to CPU. This is specific action for HW offloads. Also, the patchset offloads the action to mlxsw driver.
Example usage: $ tc filter add dev enp3s0np19 parent ffff: protocol ip prio 20 flower skip_sw dst_ip 192.168.10.1 action trap Jiri Pirko (6): net: sched: introduce a TRAP control action net: sched: introduce helper to identify gact trap action mlxsw: pci: Fix size of trap_id field in CQE mlxsw: spectrum: Introduce ACL trap acl: Introduce ACL trap action spectrum_flower: Implement gact trap TC action offload .../mellanox/mlxsw/core_acl_flex_actions.c | 40 ++++++++++++++++++++-- .../mellanox/mlxsw/core_acl_flex_actions.h | 1 + drivers/net/ethernet/mellanox/mlxsw/pci_hw.h | 2 +- drivers/net/ethernet/mellanox/mlxsw/spectrum.c | 4 ++- drivers/net/ethernet/mellanox/mlxsw/spectrum.h | 1 + drivers/net/ethernet/mellanox/mlxsw/spectrum_acl.c | 5 +++ .../net/ethernet/mellanox/mlxsw/spectrum_flower.c | 4 +++ drivers/net/ethernet/mellanox/mlxsw/trap.h | 1 + include/net/tc_act/tc_gact.h | 15 ++++++-- include/uapi/linux/pkt_cls.h | 5 +++ net/core/dev.c | 2 ++ net/sched/cls_bpf.c | 1 + net/sched/sch_atm.c | 1 + net/sched/sch_cbq.c | 1 + net/sched/sch_drr.c | 1 + net/sched/sch_dsmark.c | 1 + net/sched/sch_fq_codel.c | 1 + net/sched/sch_hfsc.c | 1 + net/sched/sch_htb.c | 1 + net/sched/sch_multiq.c | 1 + net/sched/sch_prio.c | 1 + net/sched/sch_qfq.c | 1 + net/sched/sch_sfb.c | 1 + net/sched/sch_sfq.c | 1 + 24 files changed, 87 insertions(+), 6 deletions(-) -- 2.9.3
