Cannot get WPA_supplicant work for TPlink 725 wireless adapter for P2P

[Abhinav Sinha]

I have TP-link 725 adapter that has P2P support that cant be verified via
iwpriv:
$ iwpriv
wlan1     Available private ioctls :
          write            (8BE0) : set 2047 char  & get   0
          read             (8BE1) : set 2047 char  & get  16 char
          driver_ext       (8BE2) : set   0       & get   0
          mp_ioctl         (8BE3) : set   0       & get   0
          apinfo           (8BE4) : set   1 int   & get   0
          setpid           (8BE5) : set   2 int   & get   0
          wps_start        (8BE6) : set   1 int   & get   0
          get_sensitivity  (8BE7) : set   1 int   & get   0
          wps_prob_req_ie  (8BE8) : set   1 int   & get   0
          wps_assoc_req_ie (8BE9) : set   1 int   & get   0
          channel_plan     (8BEA) : set   1 int   & get   0
          dbg              (8BEB) : set   2 int   & get   0
          rfw              (8BEC) : set   3 int   & get   0
          rfr              (8BED) : set   2 int   & get  16 char
          p2p_set          (8BF0) : set  64 char  & get   0
          p2p_get          (8BF1) : set  64 char  & get  64 char
          p2p_get2         (8BF2) : set  64 char  & get  16 char
...

Rest removed for brevity.

However, in attempt to make a generic application, I want to use
wpa_supplicant.
But I am not apble to get it to work.

Here are few of my trials:
1)
wpa_supplicant-2.3/wpa_supplicant$ sudo ./wpa_supplicant -iwlan1 -Dnl80211
-C/var/run/wpa_supplicant2.3
Successfully initialized wpa_supplicant
nl80211: Could not configure driver mode
wlan1: Failed to initialize driver interface
2)
I am able to launch with -Dwext but it does not give positive response for
any p2p commands.

Please suggest on How to configure wpa_supplicant to launch with this
dongle for P2P support.
