From ff2ebbfba6186adf3964eb816f8f255c6e664dc4 Mon Sep 17 00:00:00 2001 From: Hoang Le Date: Tue, 19 Mar 2019 18:49:49 +0700 Subject: tipc: introduce new capability flag for cluster As a preparation for introducing a smooth switching between replicast and broadcast method for multicast message, We have to introduce a new capability flag TIPC_MCAST_RBCTL to handle this new feature. During a cluster upgrade a node can come back with this new capabilities which also must be reflected in the cluster capabilities field. The new feature is only applicable if all node in the cluster supports this new capability. Acked-by: Jon Maloy Signed-off-by: Hoang Le Signed-off-by: David S.
