** Description changed: [Impact] MT7921 is disabled by default, and it affects the power consumption. [Fix] MTK pointed out we need this commit which is included in v5.16-rc1 - bf3747ae2e25 mt76: mt7921: enable aspm by default + bf3747ae2e25 mt76: mt7921: enable aspm by default + After ASPM is enabled, we found the card disappears after reboot sometimes, so MTK provides another commit for it + https://patchwork.kernel.org/project/linux-mediatek/patch/70e27cbc652cbdb78277b9c691a3a5ba02653afb.1641540175.git.obj...@gmail.com/ [Test] Verified on Dell machines with MT7921 wifi card. [Where problems could occur] - Enable device ASPM is always risky, but MT7921 is a rather new device, - and MTK submitted the patch at June, so it should be safe to enable ASPM - on this new device and there is no follow up fixes commit after ASPM is enabled. + Enable device ASPM is always risky, we've done our best to test these patches, and no regression could be found.
