From 4d8642d896c53966d32d5e343c3620813dd0e7c8 Mon Sep 17 00:00:00 2001 From: Jon Paul Maloy Date: Tue, 3 Jan 2017 10:55:10 -0500 Subject: tipc: modify struct tipc_plist to be more versatile During multicast reception we currently use a simple linked list with push/pop semantics to store port numbers. We now see a need for a more generic list for storing values of type u32. We therefore make some modifications to this list, while replacing the prefix 'tipc_plist_' with 'u32_'. We also add a couple of new functions which will come to use in the next commits. Acked-by: Parthasarathy Bhuvaragan Acked-by: Ying Xue Signed-off-by: Jon Maloy Signed-off-by: David S.
