Jiri Pirko says:

====================
mlxsw: Introduce support for "pass" gact action offloading

Very simple patchset adds ability for user to insert filters with "pass"
gact action and offload it. That allows scenarios like this:

$ tc filter add dev enp3s0np19 ingress protocol ip pref 10 flower skip_sw dst_ip 192.168.101.0/24 action drop
$ tc filter add dev enp3s0np19 ingress protocol ip pref 9 flower skip_sw dst_ip 192.168.101.1 action pass
====================
