ATH10K set bitrates problem

ATH10K set bitrates problem

[Frank Agius]

I am unable to set the bitrates for devices using the ath10k driver, 
regardless of the arguments I pass:


# iw wlan0 set bitrates legacy-2.4 6 12 24
command failed: Invalid argument (-22)
# iw dev wlan0 set bitrates mcs-2.4 10
command failed: Invalid argument (-22)


The ath10k drivers were built from stable backports v3.15-rc1.   I am 
using firmware file firmware-2.bin_999.999.0.636


Is this a known issue?

This is expected.
ath10k support only single rate setting (or single nss). So, please
check commit message,
ath10k: add set_bitrate_mask callback

Try this:
iw wlan0 set bitrates legacy-2.4 18 ht-mcs-2.4
iw wlan0 set bitrates legacy-2.4 ht-mcs-2.4 6
iw wlan0 set bitrates - back to default mask.

Thanks, using the bitrate option ht-mcs-2.4 instead of mcs-2.4 worked.  
Note that I did have to upgrade the iw tools package.  The version I was 
using (3.11) does not have support for bitrate option ht-mcs.  Version 
3.15 of iw tools does support the new options.
