---help---
Selecting this option causes mac80211 to keep additional
and very verbose statistics about TX and RX handler use
- and show them in debugfs.
+ 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.
