Packet flow stops on monitor mode, when fixed rate

Reported by: Assigned to:
Priority: minor Milestone:
Component: madwifi: driver Version: v0.9.4
Keywords: monitor rate Cc:
Patch is attached: 0 Pending: 0


When i run my card in monitor mode, and set fixed rate, packet flow stops and won't run again, or even my system hangs (depends on rate). Tested with airodump and simple tcpdump. I'm using iwconfig to configure devices.

wlanconfig  mon1 create wlandev wifi0 wlanmode monitor[[BR]]
iwconfig mon1 rate 1M[[BR]]
iwconfig mon1 rate 54M

First iwconfig command cause flow-stop problem, second hangs my system. I did't try another rates. When i set 1M rate, no messages occurs.
