---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 [31mCONFIG_MAC80211_MESSAGE_TRACING[0m
bool "Trace all mac80211 debug messages"
depends on [31mCONFIG_MAC80211[0m
---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 [31mCONFIG_MAC80211_DEBUG_MENU[0m

config [31mCONFIG_MAC80211_NOINLINE[0m
bool "Do not inline TX/RX handlers"
depends on [31mCONFIG_MAC80211_DEBUG_MENU[0m
---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 [31mCONFIG_MAC80211_VERBOSE_DEBUG[0m
bool "Verbose debugging output"
depends on [31mCONFIG_MAC80211_DEBUG_MENU[0m

---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.

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.
