This option selects the default rate control algorithm
mac80211 will use. Note that this default can still be
overridden through the ieee80211_default_rc_algo module
parameter if different algorithms are available.

config MAC80211_MESH
bool "Enable mac80211 mesh networking support"
depends on MAC80211
---help---
Select this option to enable 802.11 mesh operation in mac80211
drivers that support it. 802.11 mesh connects multiple stations
over (possibly multi-hop) wireless links to form a single logical
LAN.
config MAC80211_LEDS
bool "Enable LED triggers"
depends on MAC80211
depends on LEDS_CLASS
select LEDS_TRIGGERS
---help---
This option enables a few LED triggers for different
packet receive/transmit events.
config MAC80211_DEBUGFS
bool "Export mac80211 internals in DebugFS"
depends on MAC80211 && DEBUG_FS
---help---
Select this to see extensive information about
the internal state of mac80211 in debugfs.
Say N unless you know you need this.
config MAC80211_MESSAGE_TRACING
bool "Trace all mac80211 debug messages"
depends on MAC80211
---help---
Select this option to have mac80211 register the
mac80211_msg trace subsystem with tracepoints to
collect all debugging messages, independent of
printing them into the kernel log.
The overhead in this option is that all the messages
need to be present in the binary and formatted at
runtime for tracing.
menuconfig MAC80211_DEBUG_MENU
bool "Select mac80211 debugging features"
depends on MAC80211
---help---
This option collects various mac80211 debug settings.
config MAC80211_NOINLINE
bool "Do not inline TX/RX handlers"
depends on MAC80211_DEBUG_MENU
---help---
This option affects code generation in mac80211, when
selected some functions are marked "noinline" to allow
easier debugging of problems in the transmit and receive
paths.
This option increases code size a bit and inserts a lot
of function calls in the code, but is otherwise safe to
enable.
If unsure, say N unless you expect to be finding problems
in mac80211.
config MAC80211_VERBOSE_DEBUG
bool "Verbose debugging output"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
many debugging messages. It should not be selected
on production systems as some of the messages are
remotely triggerable.
Do not select this option.
config MAC80211_MLME_DEBUG
bool "Verbose managed MLME output"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
debugging messages for the managed-mode MLME. It
should not be selected on production systems as some
of the messages are remotely triggerable.
Do not select this option.
config MAC80211_STA_DEBUG
bool "Verbose station debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
debugging messages for station addition/removal.
Do not select this option.
config MAC80211_HT_DEBUG
bool "Verbose HT debugging"
depends on MAC80211_DEBUG_MENU
---help---
This option enables 802.11n High Throughput features
debug tracing output.
It should not be selected on production systems as some
of the messages are remotely triggerable.
Do not select this option.
config MAC80211_OCB_DEBUG
bool "Verbose OCB debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
very verbose OCB debugging messages. It should not
be selected on production systems as those messages
are remotely triggerable.
Do not select this option.
config MAC80211_IBSS_DEBUG
bool "Verbose IBSS debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out
very verbose IBSS debugging messages. It should not
be selected on production systems as those messages
are remotely triggerable.
Do not select this option.
config MAC80211_PS_DEBUG
bool "Verbose powersave mode debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out very
verbose power save mode debugging messages (when mac80211
is an AP and has power saving stations.)
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_MPL_DEBUG
bool "Verbose mesh peer link debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH
---help---
Selecting this option causes mac80211 to print out very
verbose mesh peer link debugging messages (when mac80211
is taking part in a mesh network).
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_MPATH_DEBUG
bool "Verbose mesh path debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH
---help---
Selecting this option causes mac80211 to print out very
verbose mesh path selection debugging messages (when mac80211
is taking part in a mesh network).
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_MHWMP_DEBUG
bool "Verbose mesh HWMP routing debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH
---help---
Selecting this option causes mac80211 to print out very
verbose mesh routing (HWMP) debugging messages (when mac80211
is taking part in a mesh network).
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_MESH_SYNC_DEBUG
bool "Verbose mesh synchronization debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH

synchronization debugging messages (when mac80211 is taking part in a
mesh network).
Do not select this option.
config MAC80211_MESH_CSA_DEBUG
bool "Verbose mesh channel switch debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH
---help---
Selecting this option causes mac80211 to print out very verbose mesh
channel switch debugging messages (when mac80211 is taking part in a
mesh network).
Do not select this option.
config MAC80211_MESH_PS_DEBUG
bool "Verbose mesh powersave debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_MESH
---help---

powersave debugging messages (when mac80211 is taking part in a
mesh network).
Do not select this option.
config MAC80211_TDLS_DEBUG
bool "Verbose TDLS debugging"
depends on MAC80211_DEBUG_MENU
---help---
Selecting this option causes mac80211 to print out very
verbose TDLS selection debugging messages (when mac80211
is a TDLS STA).
It should not be selected on production systems as those
messages are remotely triggerable.
Do not select this option.
config MAC80211_DEBUG_COUNTERS
bool "Extra statistics for TX/RX debugging"
depends on MAC80211_DEBUG_MENU
depends on MAC80211_DEBUGFS
---help---
Selecting this option causes mac80211 to keep additional
and very verbose statistics about TX and RX handler use
as well as a few selected dot11 counters. These will be
exposed in debugfs.
Note that some of the counters are not concurrency safe
and may thus not always be accurate.
If unsure, say N.
config MAC80211_STA_HASH_MAX_SIZE
int "Station hash table maximum size" if MAC80211_DEBUG_MENU
default 0
---help---
Setting this option to a low value (e.g. 4) allows testing the
hash table with collisions relatively deterministically (just
connect more stations than the number selected here.)
If unsure, leave the default of 0.
