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

45 * reclaim nodes that leave part way through the 802.1x exchange.
