How to update Access Category for QOS Control filed of MAC Header (WLAN Adapter ) and DSCP in IP Header with UDP Traffic or ICMP Traffic

Hi ,

I have to validate QOS feature  for my WLAN Driver . Associated the my WLAN adapter to the QOS capable AP  :

Case 1 : Started prioritized ping to the AP from my WLAN Client,but all packets are going with DSCP Value 0. 

Eg: ping 192.168.5.1 -v 224 -t

Case 2 : Generated the prioritized traffic with iperf  but here also all packets are going with DSCP Value 0. QOS Control field of Client MAC Header is not updating with specified access category.

iperf  -u -c 192.168.5.10 -S 224 -t 10000

Thanks,

Harsha
