o Create `struct hdlc' - a part of struct physical.
o Move our LCP report timer into struct hdlc - it's really a hdlc timer (fcs errors etc). o Make `show hdlc' require context and make the output more friendly. o Remove all non-const globals from hdlc.c o Output peer-rejected protocols by name - not just ones that we reject.
