I am testing my chip under the AP mode with hostapd. I use the kernel 3.0. I start the AP and check that all four tx queues are start, then I start a udp stream of BE from Ap to the station. After that I find other three tx queues stopped. I am sure that my driver dose not stop them. Is this a kernel machinesm ? Thanks
