Now b43 won't send any unicast frames to N800 according to a wireless sniffer (and packet loss is 100%, obviously). Broadcast frames are sent and N800 replies to ARP requests just fine. I was a bit surprised by the result, so I double checked my tests. After reverting this patch unicast frames were sent again, just that QoS frames were broken as expected. So this patch definetely broke unicast QoS send. Tested with wireless-dev#anything commit 60faa0c2 and N800 had PSM disabled. I didn't have time to test with QoS disabled, sorry. But I can test that later, if you want. -- Kalle Valo - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
