From: Johannes Berg <johannes.berg@xxxxxxxxx> According to the spec, VHT doesn't exist in 2.4GHz. There are vendor extensions to allow a subset of VHT to work (notably 256-QAM), but since mac80211 doesn't support those advertising VHT capability on 2.4GHz leads to the behaviour of reporting VHT capabilities but not being able to use any of them due to mac80211's code requiring 80 MHz support. Remove the VHT capabilities from 2.4GHz for now. If mac80211 gets extended to use the (likely Broadcom) vendor IEs for it and handles the lack of 80 MHz support, it can be added back.

The thing is, it actually works just fine with the patch I posted to fix mac80211, and at any rate, even if the mac80211 patch isn't applied, the ath10k driver works just fine in HT mode. Have you actually found any case where the existing behaviour causes a real problem?
