o Alter the mbuf type as it's processed by different layers.

Browse Source 
o Show more information about missing MP fragments in ``show mp''.
o Do away with mbuf_Log().  It was showing mbuf stats twice on
  receipt of LCP/CCP/IPCP packets.... ???!!?
o Pre-allocate a bit extra when creating LQR packets to avoid having
  to allocate another mbuf in mbuf_Prepend().
