  78         This options enables support of Draft 802.11s mesh networking.
  79         The implementation is based on Draft 2.08 of the Mesh Networking
  80         amendment.  However, no compliance with that draft is claimed or even
  81         possible, as drafts leave a number of identifiers to be defined after
  82         ratification.  For more information visit http://o11s.org/.
