Function Documentation

int caif_connect_client	(	struct net *	net,
		struct caif_connect_request *	conn_req,
		struct cflayer *	client_layer,
		int *	ifindex,
		int *	headroom,
		int *	tailroom
	)

caif_connect_client - Connect a client to CAIF Core Stack. : Channel setup parameters, specifying what address to connect on the Modem. : User implementation of client layer. This layer MUST have receive and control callback functions implemented. : Link layer interface index used for this connection. : Head room needed by CAIF protocol. : Tail room needed by CAIF protocol.

This function connects a CAIF channel. The Client must implement the struct cflayer. This layer represents the Client layer and holds receive functions and control callback functions. Control callback function will receive information about connect/disconnect responses, flow control etc (see enum caif_control). E.g. CAIF Socket will call this function for each socket it connects and have one client_layer instance for each socket.

int caif_disconnect_client	(	struct net *	net,
		struct cflayer *	client_layer
	)

caif_disconnect_client - Disconnects a client from the CAIF stack.

: Client layer to be disconnected.

		struct cflayer *	phy_layer,
		enum cfcnfg_phy_preference	pref,

	)

cfcnfg_add_phy_layer() - Adds a physical layer to the CAIF stack. : Pointer to a CAIF configuration object, created by cfcnfg_create(). : Pointer to link layer device : Specify the physical layer. The transmit function MUST be set in the structure. : The phy (link layer) preference. : Protocol implementation for link layer specific protocol. : Specify if checksum is used in CAIF Framing Layer. : Head space needed by link specific protocol.
