[v2,2/4] wifi: ath11k: push MU-MIMO params from hostapd to hardware

Commit Message

Muna Sinada Oct. 18, 2022, 9:28 p.m. UTC

In the previous behaviour only HE IE in management frames are changed
regarding MU-MIMO configurations and not in hardware. Adding push of
MU-MIMO configurations to the hardware as well.

This patch is dependant on mac80211 patchset:
https://patchwork.kernel.org/project/linux-wireless/list/?series=683322&state=%2A&archive=both

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00356-QCAHKSWPL_SILICONZ-1

Hi,
This is causing a regression for us in OpenWrt at least on IPQ8074 but
probably on all ath11k-supported HW.
Cause 80+80 and 160MHz support bits are being cleared here so 160MHz
is not being advertised after this patch.

I fail to understand why are 80+80 and 160 MHz feature flags being cleared?

Regards,
Robert

Oh man, not good. Robert, should we revert this patchset entirely? Of
course it would be better if Muna can submit quickly a fix, but I'm not
going to wait for long.

The patchset is in wireless-next at the moment and the commits from the
patchset are:

a96f10422e74 wifi: ath11k: modify accessor macros to match index size
38dfe775d0ab wifi: ath11k: push MU-MIMO params from hostapd to hardware
8077c1bbbc28 wifi: ath11k: move HE MCS mapper to a separate function
ebf82988f844 wifi: ath11k: generate rx and tx mcs maps for supported HE mcs

> I fail to understand why are 80+80 and 160 MHz feature flags being cleared?

Me neither. I missed that in my review.

I would prefer to see it get fixed, cause just removing the flag
removal gets 160MHz working,
but I am not sure about other flags as well.

Ok, let's try to get it fixed then. Muna, can you comment and send a fix
ASAP?

No reply from Muna. I'll try the new bugbot to open a bug for this regression:

I have created fix, tested it and pushed internally for review.

@Kalle, how do I go about continuing the conversation on Bugzilla?

Better to continue the discussion on the list. I only created the bug on
Bugzilla so that I don't forget this as I didn't hear anything from you.

Muna now submitted a fix:

Robert, can you please check it? And if it works a Tested-by would be
nice.

Hi,
I already saw it and gave it a quick test, for me it brings up 160MHz
and I have requested some more testing from other community members.
I will reply with my Tested-by tag.

Thanks for fixing the issue.

Robert
