  21          This option enables a TX rate control algorithm for
  22          mac80211 that uses a PID controller to select the TX
  23          rate.

  69         This options enables support of Draft 802.11s mesh networking.
  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
 118          paths.
 119
 120          This option increases code size a bit and inserts a lot
 121          of function calls in the code, but is otherwise safe to
 122          enable.

 125          in mac80211.
