From 3b1903ef97c080a80ead3a6a2305f55108e08269 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 2 Feb 2019 12:50:47 +0100 Subject: [PATCH] flow_offload: add statistics retrieval infrastructure and use it This patch provides the flow_stats structure that acts as container for tc_cls_flower_offload, then we can use to restore the statistics on the existing TC actions. Hence, tcf_exts_stats_update() is not used from drivers anymore. Signed-off-by: Pablo Neira Ayuso Acked-by: Jiri Pirko Signed-off-by: David S.
