I didn't found a forum topic for QCA9984 so i post my problem here !

I'm using OpenWRT on Netgear R7800 with Qualcomm QCA9984 wifi module, I would like to extract WMM Infos especially:
*TXOP: Time interval during which a station can send as many frames as possible (global free air time on the BSS)
*TXretrans: Number of frame retransmissions on the BSS
*sync_rate: all physical rates used in Mbp
And I didn't found a way to extract those Infos,
 can anyone help me in my issue?

 Are you trying to extract this info in user space or in application?
 
> txop will vary based on Access Category (AC) and your AP dictates TXOP for each AC for STA and itself
Example to check: iwpriv athx get_txoplimit 0 1
This will tell what the txop limit is for the STA to use for AC 0 (Best effort)
For txop: 1st value is the AC level, 2nd value is whether you are checking it for AP or STA
 
> athstats -i wifix : will display stats like Tx Retransmissions
 
> If you mean sync_rates as what rates the AP uses
iwpriv athx get_mode : will tell overall operating mode.  For example on 2.4G it may show 11NGH720 Where HT20 means it supports 11N rates
athstats -i wifiX | grep stats  : will show MCS stats

Thank you raja_pedada for your reply
> i had been trying with iwpriv and this is the output :
 -----------------------------------------------------
root@OpenWrt:~# iwpriv
eth0      no private ioctls.

eth0.2    no private ioctls.

eth1      no private ioctls.

eth1.1    no private ioctls.

br-lan    no private ioctls.

wlan1     no private ioctls.

lo        no private ioctls.

wlan0     no private ioctls.

>I try  iwpriv athx get_txoplimit 0 1  with the wifi interfaces(wlan0 & wlan1) and ath10k but always the same output : no private ioctls.
>I can't found a way to install athstats in openwrt !

>In an other project,i was working with CYPRESS chipset. I was able to extract this Infos by integrating the manufacturing firmware of the chipset and WL command sent by the constructor. Is there for Qualcomm chipset some tools like WL command that could help me??
