  25          This option enables a TX rate control algorithm for
  26          mac80211 that uses a PID controller to select the TX

  48          This option selects the default rate control algorithm
  49          mac80211 will use. Note that this default can still be

  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/.

 112        depends on MAC80211
 113        ---help---
 114          Select this option to have mac80211 register the
 115          mac80211_msg trace subsystem with tracepoints to
 116          collect all debugging messages, independent of
 117          printing them into the kernel log.
 118
 119          The overhead in this option is that all the messages
 120          need to be present in the binary and formatted at
 121          runtime for tracing.

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

 143          in mac80211.

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