a79a1cb03fa9ca71b825e72f880b344e1 Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Sat, 4 Feb 2017 18:05:07 +0100 Subject: bridge: move to workqueue gc Move the fdb garbage collector to a workqueue which fires at least 10 milliseconds apart and cleans chain by chain allowing for other tasks to run in the meantime. When having thousands of fdbs the system is much more responsive. Most importantly remove the need to check if the matched entry has expired in __br_fdb_get that causes false-sharing and is completely unnecessary if we cleanup entries, at worst we'll get 10ms of traffic for that entry before it gets deleted.
