From 9674c2e68c613757ddf5a8780743842b5ac4d74f Mon Sep 17 00:00:00 2001 From: Lutz Donnerhacke Date: Tue, 12 Jan 2021 22:28:29 +0100 Subject: netgraph/ng_bridge: become SMP aware The node ng_bridge underwent a lot of changes in the last few months. All those steps were necessary to distinguish between structure modifying and read-only data transport paths. Now it's done, the node can perform frame forwarding on multiple cores in parallel.
