Note that this default can still be overridden through the ieee80211_default_rc_algo module parameter if different algorithms are available. config MAC80211_RC_DEFAULT_MINSTREL bool "Minstrel" depends on MAC80211_RC_MINSTREL ---help--- Select Minstrel as the default rate control algorithm. endchoice config MAC80211_RC_DEFAULT string default "minstrel_ht" if MAC80211_RC_DEFAULT_MINSTREL default "" endif comment "Some wireless drivers require a rate control algorithm" depends on MAC80211 && MAC80211_HAS_RC=n 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 ---help--- Selecting this option causes mac80211 to print out very verbose 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--- Selecting this option causes mac80211 to print out very verbose mesh 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.
