From 03a509740b5d29705c12c4f3c6c0a2d6120201a7 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 11 Apr 2024 19:56:45 +0300 Subject: [PATCH] wifi: ath12k: enable WIPHY_FLAG_DISABLE_WEXT ath12k will support Multi-Link Operation (MLO) in the future but not yet. A major change with MLO is that cfg80211 will disable Wireless Extension (WEXT) user space interface. To avoid having inconsistent user experience, first supporting WEXT and later not, disable WEXT already now. Now ath12k claims that WEXT is not supported: $ iwconfig wlan0 wlan0 no wireless extensions.
