> MediaTek already have the commit 116c69603b01 ("mt76: mt7921: Add AP mode support") upstream. But it's based on kernel 5.18. Mediatek also suggest to add patch https://patchwork.kernel.org/project/linux-wireless/patch/21366e8bc70573794b5f12372f2e55e9059d8457.1654691030.git.deren.wu@mediatek.com/ which is already accepted by upstream to fix bug in AP mode. Enable AP mode on specific kernel versions.
