From d3d9b4fca3636bb2dc75e2eb2e4e384bbf5e4159 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 9 Dec 2020 23:16:50 +0200 Subject: iwlwifi: mvm: purge the BSS table upon firmware load When the firmware is loaded, its internal timer (GP2) is reset and all the time_sync in the BSS table is now unusable.
