How to check device has WiFi Direct capability

I want to setup WiFi direct on my target.

Output of iw list

Supported interface modes:
     * IBSS
     * managed
     * AP
Band 1:

Band 2:
    software interface modes (can always be added):
    valid interface combinations:
         * #{ IBSS, managed, AP, P2P-client, P2P-GO } <= 4,
           total <= 4, #channels <= 2, STA/AP BI must match

Looking at the above output I have following doubts:

1. How can I confirm whether my device supports WiFi direct feature or not.
2. What are software interface modes (can they be configured to WiFi Direct)

I tried the steps mentioned in particular link

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_WiFi_Direct_Configuration_Scripts#P2P_usecases

But when I run p2p_find under wpa_cli terminal it every time it returns FAIL

Please guide where I am going wrong and how can I setup and configure WiFi direct in my target.

Thanks in advance.

Wi-Fi Direct feature was disabled in the driver installed, so I was not able to configure my device for Wi-Fi direct.

So to answer my questions, this is the output of iw list after enabling the Wi-Fi direct bit in driver module.

Supported interface modes:
     * IBSS
     * managed
     * AP
     * P2P client
     * P2P Go
Band 1:

Band 2:
    software interface modes (can always be added):
    valid interface combinations:
         * #{ IBSS, managed, AP, P2P-client, P2P-GO } <= 4,
           total <= 4, #channels <= 2, STA/AP BI must match

What are software interface modes (can they be configured to WiFi Direct)?

Software interface modes suggests the different interface modes supported by the driver but all may not be enabled at present.

All the enabled interfaces are listed under Supported interface modes:
