From 63b43924294da6cb177d0509120b2e957580441c Mon Sep 17 00:00:00 2001 From: Miroslav Lichvar Date: Mon, 31 May 2021 11:07:52 +0200 Subject: [PATCH 1/54] clock: Reset state when switching port with same best clock. When the best port is changed, but the ID of the best clock doesn't change (e.g. a passive port is activated on link failure), reset the current delay and other master/link-specific state to avoid the switch throwing the clock off.
