From 90e477379e92c110a34ca0d108aa97d5b02076ee Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Mon, 29 Jul 2019 02:04:51 -0700 Subject: ice: silence some bogus error messages In some circumstances, VF devices can be deactivated while a message is in-flight. In that case, a series of scary error message will be printed in the log. Since these are actually harmless, check for this case and suppress them. No harm, no foul.
