Merge branch 'net-trap-control-action'
Jiri Pirko says:
====================
net: introduce trap control action to tc and offload it
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
v1->v2:
- patch 1
- fix the comment according to Andrew's note
