Description:

As of v2.8 Open vSwitch may program flows into the kernel and hardware using TC-Flower. This is a mechanism to allow acceleration of OvS using hardware such as Netronome SmartNICs.

The scope of this bug is to add set-action support to TC-based offload of Open vSwitch.

Accepted upstream for inclusion in v2.9.
