  86          This options enables support of Draft 802.11s mesh networking.
  87          The implementation is based on Draft 2.08 of the Mesh Networking
  88          amendment.  However, no compliance with that draft is claimed or even
  89          possible, as drafts leave a number of identifiers to be defined after
