Added new feature to get PPP/ISDN support:

enum {
	GLIBTOP_PPP_STATE_UNKNOWN = 0,
	GLIBTOP_PPP_STATE_HANGUP,
	GLIBTOP_PPP_STATE_ONLINE
};

struct _glibtop_ppp
{
	u_int64_t	flags,
		state,			/* GLIBTOP_PPP_STATE		*/
		bytes_in,		/* GLIBTOP_PPP_BYTES_IN		*/
		bytes_out;		/* GLIBTOP_PPP_BYTES_OUT	*/
};

Currently only implemented in the FreeBSD port with ISDN via I4B. - Martin
