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

This patch has no implications on HT, and I wasn't planning on applying
the mac80211 patch.
Yeah, makes sense. I'm planning to apply this soon.
As I said, I have no objections to doing the (Broadcom) vendor specific
IEs for "VHT" in 2.4 GHz band, but I don't think we should advertise
the spec IEs when they're explicitly specified to be used only in the
5.2 GHz band.
But we really should have this, any volunteers? :) I think it shouldn't
be too hard to do so this would be a good project for someone looking
for a simple, but useful, task on wireless stack.
Are these Broadcom IEs documented somewhere? If yes,
then its a matter of parsing them and adding support to
minstrel_ht, isn't it? major work would be in minstrel.
For ath10k, rate-ctrl is done in the firmware, so
no work at all in minstrel-ht.
The end result, as far as I can tell,
is you would just have to tell mac80211 to allow
VHT on 2.4Ghz, and revert this patch that Kalle is proposing.
Maybe someone that actually knows about these IEs can explain why
they are worth using?
Thanks,
Ben
