wpa_supplicant in ad-hoc mode, using wpa on a Linux 3 kernel

[Kees-Jan Hermans]

Is it at all possible ? iwconfig and kismet confirm that I keep sending
in plaintext mode, even when I set a 'psk' in the wpa_supplicant config.

ap_scan=2
network={
  ssid="adhoc"
  mode=1
  frequency=2412
  proto=WPA
  key_mgmt=WPA-NONE
  pairwise=NONE
  group=TKIP
  psk="testkey1"
}

The board is an Alix board, Voyage linux 0.8, 3.0 kernel. Device is a
WLM54AG (atheros).

Cheers,
