void l2_packet_deinit ( struct l2_packet_data l2  ) 

l2_packet_deinit - Deinitialize l2_packet interface : Pointer to internal l2_packet data from l2_packet_init()

static void l2_packet_deinit_timeout ( void *  eloop_ctx,

int l2_packet_get_ip_addr ( struct l2_packet_data l2,
char *  buf,
size_t  len 
)

l2_packet_get_ip_addr - Get the current IP address from the interface : Pointer to internal l2_packet data from l2_packet_init() : Buffer for the IP address in text format : Maximum buffer length Returns: 0 on success, -1 on failure

This function can be used to get the current IP address from the interface bound to the l2_packet. This is mainly for status information and the IP address will be stored as an ASCII string. This function is not essential for wpa_supplicant operation, so full implementation is not required. l2_packet implementation will need to define the function, but it can return -1 if the IP address information is not available.

int l2_packet_get_own_addr ( struct l2_packet_data l2,
u8 addr 
)

l2_packet_get_own_addr - Get own layer 2 address : Pointer to internal l2_packet data from l2_packet_init() : Buffer for the own address (6 bytes) Returns: 0 on success, -1 on failure

void l2_packet_notify_auth_start ( struct l2_packet_data l2  ) 

l2_packet_notify_auth_start - Notify l2_packet about start of authentication : Pointer to internal l2_packet data from l2_packet_init()

This function is called when authentication is expected to start, e.g., when association has been completed, in order to prepare l2_packet implementation for EAPOL frames. This function is used mainly if the l2_packet code needs to do polling in which case it can increasing polling frequency. This can also be an empty function if the l2_packet implementation does not benefit from knowing about the starting authentication.

int l2_packet_send ( struct l2_packet_data l2,
const u8 dst_addr,
u16  proto,
const u8 buf,
size_t  len 
)

l2_packet_send - Send a packet : Pointer to internal l2_packet data from l2_packet_init() : Destination address for the packet (only used if l2_hdr == 0) : Protocol/ethertype for the packet in host byte order (only used if l2_hdr == 0) : Packet contents to be sent; including layer 2 header if l2_hdr was set to 1 in l2_packet_init() call. Otherwise, only the payload of the packet is included. : Length of the buffer (including l2 header only if l2_hdr == 1) Returns: >=0 on success, <0 on failure
