70 The implementation is based on Draft 2.08 of the Mesh Networking
71 amendment. However, no compliance with that draft is claimed or even
72 possible, as drafts leave a number of identifiers to be defined after
73 ratification. For more information visit http://o11s.org/.

103 This option is recommended for driver authors and strongly
104 discouraged for everybody else, it will trigger a warning
105 when a driver hands mac80211 a buffer that is aligned in
106 a way that will cause problems with the IP stack on some
107 architectures.

115 This option affects code generation in mac80211, when
116 selected some functions are marked "noinline" to allow
117 easier debugging of problems in the transmit and receive
