From 44f8658017419dccbeefe64f30122fa191d0e173 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Sat, 7 Mar 2020 12:40:20 +0100 Subject: sched: act: allow user to specify type of HW stats for a filter Currently, user who is adding an action expects HW to report stats, however it does not have exact expectations about the stats types. That is aligned with TCA_ACT_HW_STATS_TYPE_ANY. Allow user to specify the type of HW stats for an action and require it. Pass the information down to flow_offload layer.
