Subject: [patch net-next 0/6] introduce trap control action to tc and offload it

From: Jiri Pirko <jiri@...lanox.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
