This one seems to be the culprit. In the !dev->dbdc_support section.

I updated the commit so that IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ is only set on MT7916, could use testing.

As hnyman pointed out in my similar pull request for mt7915 (RT3200 router) you should amend the forum link in the comment and commit to:
https://forum.openwrt.org/t/802-11ax-worse-than-802-11ac-with-mt76-driver/126466

For reference my pull request #768

Fixes buggy 802.11ax on the Redmi AX6000 when connecting to some clients.

Partially reverts https://patchwork.kernel.org/project/linux-wireless/patch/20230301163739.52314-1-nbd@nbd.name/

So any news about this? I think we have to solve this problem before 23.05 landing, and it is at RC1 now.

This applies patches from openwrt/mt76#761 and
openwrt/mt76#768 that disable 160MHz operation
on mt7915 and mt7986.

This addresses an issue in which the throughput drops dramatically with
just a few meters distance from AP, especially with Apple devices.
