The HDLC layer is still used by X.25 people (to be precise, Martin Schiller <m...@dev.tdt.de>). Although we currently have three X.25 drivers in the kernel (lapbether, x25_asy, hdlc_x25), it seems to me that only hdlc_x25 is used in the real world. So I guess the HDLC layer will be there as long as the X.25 stack is still there.
