From 6a56e19902af01da447cd3104d5a6e8d01792ee1 Mon Sep 17 00:00:00 2001 From: Baowen Zheng Date: Fri, 12 Mar 2021 15:08:30 +0100 Subject: flow_offload: reject configuration of packet-per-second policing in offload drivers A follow-up patch will allow users to configures packet-per-second policing in the software datapath. In preparation for this, teach all drivers that support offload of the policer action to reject such configuration as currently none of them support it.
