Hi,
I am using ath10k driver with qca988x hw2.0 and trying to limit it to use
VHT MCS0-7 (iw set bitrates vht-mcs-5 2:0-7).
But the command it causing a FW crash, if it disable HW_HAS_RATE_CONTROL
no crash is observed but it still uses MCS9.
tree: wireless-drivers-next: commit#535633a5ba4ea2504fa6c33176633becf0e59339
1) If i disable HW_RATE_CONTROL, will ath10k honor
the mac80211 rates?
2) Please find below the dmesg after the crash.

Thanks Raj, with this fix the rates are 0-7, if i disable then i am
seeing 0-9, so its
working.
But i am seeing a weird issues, the moment i give bitrates command,
ath10k no longer does encryption, link is a WPA2-PSK: AES. Even after
interface up/down
it doesn't work.

Bottom posting please. I have tried your change i still see the same issue.
Right after connecting i see that packets are encrypted but once it
unset/set "bitrates" plain packets are seen in sniffer.
BTW, i am not rebooting for each driver update, just re-inserting the module,
do i need to do a reboot for each driver change?

After reboot i dont see the "unencrypted" packet issue, i will do
some more testing on limiting the rates, currently in my setup its
not reaching MCS9 so cannot verify now.
Thanks for the fixes and prompt reply.

After reboot i dont see the "unencrypted" packet issue, i will do
some more testing on limiting the rates, currently in my setup its
not reaching MCS9 so cannot verify now.
Thanks for the fixes and prompt reply.

It cannot be done. You have to use whatever rate-ctrl is baked into the
firmware.

It is unlikely to happen anytime soon. It requires significant firmware
modification (and driver too), and probably you would have to add MU-MIMO
support to minstrel if you wanted to support latest ath10k NICs.

It need not be a full pledged one, but 11ac MIMO works should be
good enough (for now).

Rajkumar,
I am still not able to make mcs9 work, so i have tried to change the Nss to 1
using iw, but that is not taking affect. This command is not taking effect.

Rajkumar,
I am still not able to make mcs9 work, so i have tried to change the Nss to 1
using iw, but that is not taking affect. This command is not taking effect.

you mean not able to fix VHT rates alone. am i right? By auto rate mode, is firmware selecting
mcs9? What is the command used for fixing vht rate?

Basically my requirement is to disable MCS8 and 9 for comparison.
to check whether ath10k honors the iw command, i used below
command. changing to 1SS, but i could see that it still transmits
using 2SS. Does your patch ignore these settings except for
adhoc mode?

You can set the number of spatial streams on the phy device. Search around
for a 'chainmask' configurable.
In general, stock ath10k firmware does not have full support for setting
arbitrary bitrates options.

Yes, i know that option but havent tried that. My intention was to limit to MCS7
so in order to verify that commands i tried to change nss.
