how to trigger a WARNING()

[Holger Schurig]

$ cd /sys/kernel/debug/libertas_wireless/eth1/subscribed_events
$ cat beacon_missed
60 N/A 1
$ cat failure_count
0 0 0
$ cat low_snr
0 0 0
$ cat low_rssi
0 0 0
$ cat high_snr
$ cat high_rssi
$


Note that high_snr/rssi yielded no output. Also look at your 
dmesg, lot's of warnigs in there:
