From 817298102b0bc936b08dfcc5fbcc2213157050f2 Mon Sep 17 00:00:00 2001 From: Richard Alpe Date: Mon, 1 Feb 2016 08:19:57 +0100 Subject: [PATCH] tipc: fix link priority propagation Currently link priority changes isn't handled for active links. In this patch we resolve this by changing our priority if the peer passes a valid priority in a state message. Reviewed-by: Jon Maloy Signed-off-by: Richard Alpe Signed-off-by: David S.
