From ea07af2e71cdf2c08251d8ead196ce1c9466e38c Mon Sep 17 00:00:00 2001 From: Stéphane Graber Date: Wed, 30 Mar 2022 15:42:45 -0400 Subject: openvswitch: Add recirc_id to recirc warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When hitting the recirculation limit, the kernel would currently log something like this: [ 58.586597] openvswitch: ovs-system: deferred action limit reached, drop recirc action Which isn't all that useful to debug as we only have the interface name to go on but can't track it down to a specific flow. With this change, we now instead get: [ 58.586597] openvswitch: ovs-system: deferred action limit reached, drop recirc action (recirc_id=0x9e) Which can now be correlated with the flow entries from OVS.
