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

114	---help---
115	  Select this option to have mac80211 register the
116	  mac80211_msg trace subsystem with tracepoints to
117	  collect all debugging messages, independent of
118	  printing them into the kernel log.
119
120	  The overhead in this option is that all the messages
121	  need to be present in the binary and formatted at
122	  runtime for tracing.

134	  This option affects code generation in mac80211, when
135	  selected some functions are marked "noinline" to allow
136	  easier debugging of problems in the transmit and receive
137	  paths.
138
139	  This option increases code size a bit and inserts a lot
140	  of function calls in the code, but is otherwise safe to
141	  enable.

149	---help---
150	  Selecting this option causes mac80211 to print out
151	  many debugging messages. It should not be selected
152	  on production systems as some of the messages are
153	  remotely triggerable.
