This bug is awaiting verification that the linux-mtk/5.15.0-1030.34
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-jammy-linux-mtk' to 'verification-done-jammy-
linux-mtk'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-mtk' to 'verification-failed-jammy-linux-mtk'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

Bug description:
  [Impact]
  The wifi hotspot on systems with Mediatek MT7921 wifi chip doesn't work.

  [Fix]
  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 bug in AP mode. Enable AP mode on 
specific kernel versions.

  [Test]
  Verified on the machines with MediaTek MT7921 chip.

  [Where problems could occur]
  The patches are to enable AP mode and and fix related issues on new VIF with 
AP capability, should have minimal impact to the origin behaviors.
