From d3e2dcdb6853ee263283121360f5facb73627cfd Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Fri, 27 Aug 2021 11:55:07 -0700 Subject: [PATCH 1/1] ionic: fire watchdog again after fw_down In some cases of fw_down it was called because there was a fw_generation change, and the firmware is already back up. In order to keep the down time to a minimum, don't wait for the next watchdog polling cycle, fire another watchdog off as soon as we can - an out-of-cycle check won't hurt, and may well speed up the recovery.
