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.

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.
