From f88c19aab5f34835f1ba467c5b508ec4f782f07f Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Thu, 17 Jan 2019 12:44:25 -0800 Subject: net_sched: add hit counter for matchall Although matchall always matches packets, however, it still relies on a protocol match first. So it is still useful to have such a counter for matchall. Of course, unlike u32, every time we hit a matchall filter, it is always a success, so we don't have to distinguish them. Sample output: filter protocol 802.1Q pref 100 matchall chain 0 filter protocol 802.1Q pref 100 matchall chain 0 handle 0x1 not_in_hw (rule hit 10) action order 1: vlan pop continue index 1 ref 1 bind 1 installed 40 sec used 1 sec Action statistics: Sent 836 bytes 10 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Reported-by: Martin Olsson Cc: Jamal Hadi Salim Cc: Jiri Pirko Signed-off-by: Cong Wang Signed-off-by: David S.
