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 its 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.
