> 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 patches https://patchwork.kernel.org/project/linux-mediatek/list/?series=648452 which are already accepted by upstream to fix bugs in AP mode. Enable AP mode on specific kernel versions.

At least the changes are partially upstream and are isolated to one driver.
