How to account traffic between 2 wireless clients in the same wifi interface?

[Rolando Martins]

Hi all,
I am unable to get traffic stats from ifconfig between 2 wireless clients within the same Wifi interface, e.g. in my case, asus 5G-1 on my AC3200 Asus with Asus-Merlin. If I have the 2 clients in different wifi interfaces then the traffic is accounted.
I am researching TDLS benefits and I need this info to check if the traffic is being through the AP or not.
It seems that the broadcom device driver is looking up the destination MAC address and performing a short-circuit on the network stack.

Is there anyway to disable this behavior?

Thanks,
Rolando
