From 008c04d53ef5af32b99dfcd502174ed05aaf80c9 Mon Sep 17 00:00:00 2001 From: Miri Korenblit Date: Thu, 13 Mar 2025 00:22:29 +0200 Subject: [PATCH] wifi: iwlwifi: mld: prevent toggling EMLSR due to FW requests We exit EMLSR mode if the FW requested to do so. To prevent repeated toggling of the EMLSR mode (frequent entry and exit), add this exit reason to the EMLSR prevention mechanism. This mechanism avoids re-entering EMLSR for a certain period of time after multiple exits caused by the same reason.
