  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
  90         ratification.  For more information visit http://o11s.org/.
