289 and very verbose statistics about TX and RX handler use
Johannes Bergc206ca62015-04-22 20:47:28 +0200[diff] [blame]290 as well as a few selected dot11 counters. These will be
291 exposed in debugfs.

293 Note that some of the counters are not concurrency safe
294 and may thus not always be accurate.

Johannes Bergebd82b32015-04-23 17:26:06 +0200[diff] [blame]302 Setting this option to a low value (e.g. 4) allows testing the
303 hash table with collisions relatively deterministically (just
304 connect more stations than the number selected here.)

306 If unsure, leave the default of 0.
