From 6536993371fab3de4e8379649b60e94d03e6ff37 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Sun, 26 Apr 2020 15:22:07 +0200 Subject: bridge: mrp: Integrate MRP into the bridge To integrate MRP into the bridge, the bridge needs to do the following: - detect if the MRP frame was received on MRP ring port in that case it would be processed otherwise just forward it as usual. - enable parsing of MRP - before whenever the bridge was set up, it would set all the ports in forwarding state. Add an extra check to not set ports in forwarding state if the port is an MRP ring port. The reason of this change is that if the MRP instance initially sets the port in blocked state by setting the bridge up it would overwrite this setting.
