From b01058ce2c79705b96aeba52e41ba986640020f0 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Mon, 27 Jan 2020 09:56:58 -0500 Subject: classify: pcap / packet trace debug CLI bugs "classify filter trace ... " and "classify filter pcap ..." are mutually exclusive. vnet_pcap_dispatch_trace_configure needs to check for set->table_indices == NULL.
