BK, VI, VO tx queue stopped unexpectedly
Hi guys
I am writing a nl80211/cfg80211 driver for my wifi chip. 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

No mac80211? In that case, it has to be your driver ... if the queues are really stopped. Or maybe you just leaked the frames and messed up completely that way...
