Define a modem PPP module and bind it to a network interface.

This macro defines the modem_ppp instance, initializes a PPP L2 network device instance, and binds the modem_ppp instance to the PPP L2 instance.

Parameters

_name	Name of the statically defined modem_ppp instance
_init_iface	Hook for the PPP L2 network interface init function
_prio	Initialization priority of the PPP L2 net iface
_mtu	Max size of net_pkt data sent and received on PPP L2 net iface
_buf_size	Size of partial PPP frame transmit and receive buffers
