From 14c04493cb77bc38404dbcb39d5ccbb667831ad7 Mon Sep 17 00:00:00 2001 From: Jon Maloy Date: Fri, 13 Oct 2017 11:04:17 +0200 Subject: tipc: add ability to order and receive topology events in driver As preparation for introducing communication groups, we add the ability to issue topology subscriptions and receive topology events from kernel space. This will make it possible for group member sockets to keep track of other group members. Signed-off-by: Jon Maloy Acked-by: Ying Xue Signed-off-by: David S.
