75 bool "Enable mac80211 mesh networking (pre-802.11s) support"
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/.
