From: Miri Korenblit Date: Tue, 16 Apr 2024 10:54:08 +0000 (+0300) Subject: wifi: iwlwifi: mvm: don't recompute EMLSR mode in can_activate_links X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a9bf72d835989d116a5662398b82cd456dc3c82e;p=linux.git wifi: iwlwifi: mvm: don't recompute EMLSR mode in can_activate_links mac80211 invokes the driver callback drv_can_activate_links() from ieee80211_set_active_links to verify it can activate the desired link combination. However, ieee80211_set_active_links is called with more than one link in 2 cases: - After driver's link selection decided to enter EMLSR - From debugfs, for testing purposes. For both cases there is no need to recompute all the considerations determining whether to activate EMLSR. Instead, only check if the vif is not blocked for EMLSR.
