Detailed Description

wpa_supplicant - TDLS

Function Documentation

void wpa_tdls_deinit

(

struct wpa_sm *

sm

)

Deinitialize driver interface parameters for TDLS.

This function is called to recover driver interface parameters for TDLS and frees resources allocated for it.

int wpa_tdls_init

(

struct wpa_sm *

sm

)

Initialize driver interface parameters for TDLS.

Parameters

wpa_s

Pointer to wpa_supplicant data

Returns

0 on success, -1 on failure

This function is called to initialize driver interface parameters for TDLS. wpa_drv_init() must have been called before this function to initialize the driver interface.

int wpa_tdls_start	(	struct wpa_sm *	sm,
		const u8 *	addr
	)

Initiate TDLS handshake (send TPK Handshake Message 1)

Parameters

sm	Pointer to WPA state machine data from wpa_sm_init()
peer	MAC address of the peer STA

Returns

0 on success, or -1 on failure

Send TPK Handshake Message 1 info to driver to start TDLS handshake with the peer.
