 Problem duplicated on FreeBSD 8.2 and wi(4) driving 
 a NETGEAR MA401RA Wireless PC Card on a AMD K6-2.
 
 kernel: wi0: <NETGEAR MA401RA Wireless PC Card> at port 0x100-0x13f irq 11 function 0 config 1 on pccard0
 
 No packets are transmitted according to tcpdump -n on another machine
 using the iwi(4) driver. 
 
 Also, wlandebug -i wlan0 debug+dumppkts+crypto+assoc+auth shows association
 activity, but no packets transmitted after this point:
 
 kernel: wlan0: send probe req on channel 10 bssid ff:ff:ff:ff:ff:ff ssid "xxxxxxxx"
 kernel: wlan0: send probe req on channel 10 bssid ff:ff:ff:ff:ff:ff ssid ""wlan0: received probe_resp from xx:xx:xx:xx:xx:xx rssi 52
 kernel: 
 kernel: wlan0: received probe_resp from xx:xx:xx:xx:xx:xx rssi 52
 kernel: wlan0: received beacon from xx:xx:xx:xx:xx:xx rssi 52
 Sep 17 12:06:37 last message repeated 3 times
 kernel: wlan0: associated with xx:xx:xx:xx:xx:xx ssid "xxxxxxxx" channel 6 start 1Mb
 kernel: wlan0: link state changed to UP
 
 Does this chipset have built-in WEP? Can we turn that off and use the (slower)
 software wlan_wep instead?
