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