36 * Each ieee80211com instance has a single timer that fires every
37 * IEEE80211_INACT_WAIT seconds to handle "inactivity processing".
38 * This is used to do node inactivity processing when operating
39 * as an AP, adhoc or mesh mode. For inactivity processing each node
40 * has a timeout set in it's ni_inact field that is decremented
41 * on each timeout and the node is reclaimed when the counter goes
42 * to zero. We use different inactivity timeout values depending
43 * on whether the node is associated and authorized (either by
44 * 802.1x or open/shared key authentication) or associated but yet
45 * to be authorized. The latter timeout is shorter to more aggressively
