From 8f2ca70c07f4cee68ed6297c1876c28b73c9af21 Mon Sep 17 00:00:00 2001 From: Oz Shlomo Date: Sun, 12 Feb 2023 15:25:12 +0200 Subject: net/sched: optimize action stats api calls Currently the hw action stats update is called from tcf_exts_hw_stats_update, when a tc filter is dumped, and from tcf_action_copy_stats, when a hw action is dumped. However, the tcf_action_copy_stats is also called from tcf_action_dump. As such, the hw action stats update cb is called 3 times for every tc flower filter dump. Move the tc action hw stats update from tcf_action_copy_stats to tcf_dump_walker to update the hw action stats when tc action is dumped.
