From 90b6f9c098512b72b77028893e42f60316409fb1 Mon Sep 17 00:00:00 2001 From: Yevhen Orlov Date: Sat, 1 Oct 2022 12:34:12 +0300 Subject: net: marvell: prestera: add delayed wq and flush wq on deinit Flushing workqueues ensures, that no more pending works, related to just unregistered or deinitialized notifiers. After that we can free memory. Delayed wq will be used for neighbours in next patches.
