Hi,

 I tried testing for Ad-Hoc mode support with wpa supplicant-0.6.1.

wpa_supplicant.conf has following entries.
------------------------------start--------------------------------------------------------------
ctrl_interface=/var/run/wpa_supplicant
ap_scan=2

network={
        ssid="kk"
        mode=1
        frequency=2462
        key_mgmt=NONE
}
------------------------------start--------------------------------------------------------------

My iwlist scan result...

# iwlist eth0 scan
eth0      Scan completed :
          Cell 03 - Address: 02:E0:98:05:56:A6
                    ESSID:"kk" [3]
                    Mode:Ad-Hoc
                    Frequency:2.462 GHz (Channel 11)
                    Quality:0/100  Signal level=-58 dBm  Noise level=-98 dBm
                    Encryption key:off
                    Bit Rates:54 Mb/s


After enabling wpa supplicant as below, it is getting connected.
------------------------------------------------------------------
# ./wpa_supplicant -ieth0 -c ./files/wpa_supplicant.adhoc -Dwext -B
ioctl[SIOCSIWPMKSA]: Invalid argument
ioctl[SIOCSIWPMKSA]: Invalid argument
# iwconfig
eth0      MRVL-SD8686  ESSID:"kk" [3]
          Mode:Ad-Hoc  Frequency:2.462 GHz  Cell: 02:E0:98:05:62:CB
          Bit Rate:54 Mb/s   Tx-Power=13 dBm
          Retry limit:8   RTS thr=2347 B   Fragment thr=2346 B
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:160
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:379693
          Tx excessive retries:234  Invalid misc:59670   Missed beacon:0



Now I modified ssid="gsdgdg" in wpa_supplicant.conf. still it is
getting connected to some MAC, which is not displayed by "iwlist eth0
scan"
Even tried by modifying frequency=162 or some junk value. now iwconfig
had yield following result

# iwconfig
eth0      MRVL-SD8686  ESSID:"gsdgdg"
          Mode:Ad-Hoc  Frequency:2.437 GHz  Cell: 02:24:F4:14:0B:E7
          Bit Rate:11 Mb/s   Tx-Power=18 dBm
          Retry limit:8   RTS thr=2347 B   Fragment thr=2346 B
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:160
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:621730
          Tx excessive retries:494  Invalid misc:125970   Missed beacon:0


Can any body tell me why this is happenning? Is it a bug in 0.6.1? or
I am doing something wrong.
