From 4b3a61b030d1131dcf3633a276158a3d0a435a47 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Sat, 30 May 2020 18:09:47 +0000 Subject: bridge: mrp: Set the priority of MRP instance Each MRP instance has a priority, a lower value means a higher priority. The priority of MRP instance is stored in MRP_Test frame in this way all the MRP nodes in the ring can see other nodes priority. Signed-off-by: Horatiu Vultur Signed-off-by: David S.
