62 ---help---
63 Select this option to enable 802.11 mesh operation in mac80211
64 drivers that support it. 802.11 mesh connects multiple stations
65 over (possibly multi-hop) wireless links to form a single logical
66 LAN.

90 Select this option to have mac80211 register the
91 mac80211_msg trace subsystem with tracepoints to
92 collect all debugging messages, independent of
93 printing them into the kernel log.
94
95 The overhead in this option is that all the messages
96 need to be present in the binary and formatted at
97 runtime for tracing.

109 This option affects code generation in mac80211, when
110 selected some functions are marked "noinline" to allow
111 easier debugging of problems in the transmit and receive
112 paths.
113
114 This option increases code size a bit and inserts a lot
115 of function calls in the code, but is otherwise safe to
116 enable.
