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.
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.
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?

iw set bitrates vht-mcs-5 1:0-7

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.

Thanks,
Ben
