From b31b77b73d65d5b0a763243ca3a5c3fda3b02816 Mon Sep 17 00:00:00 2001 From: Miri Korenblit Date: Mon, 6 May 2024 10:04:18 +0300 Subject: wifi: iwlwifi: mvm: don't request statistics in restart During restart mac80211 notifies the driver about the association, (if we was associated before the restart) which causes the driver to request statistics from the FW. This causes to an immediate exit from EMLSR after the restart is done, when the statistics notif is handled. (too low TPT). There is no point in requesting statistics wnyway, since the FW just started and don't have any.
