From fcb34635854a5a5814227628867ea914a9805384 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Fri, 4 Jun 2021 12:37:47 +0200 Subject: net: bridge: mrp: Update ring transitions. According to the standard IEC 62439-2, the number of transitions needs to be counted for each transition 'between' ring state open and ring state closed and not from open state to closed state. Therefore fix this for both ring and interconnect ring. Signed-off-by: Horatiu Vultur Signed-off-by: David S.
