From 5010bbd3c44d9fb061818be7a291a474608f510a Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Mon, 28 Nov 2022 13:13:24 +0100 Subject: stats: add boot time in stats segment Write time into /sys/boottime on VPP start. This allows a stateless control plane agent to validate if it's reconnecting to the same VPP instance.
