86  * Each ieee80211com instance has a single timer that fires once a
87  * second.  This is used to initiate various work depending on the
88  * state of the instance: scanning (passive or active), ``transition''
89  * (waiting for a response to a management frame when operating
90  * as a station), and node inactivity processing (when operating
91  * as an AP).  For inactivity processing each node has a timeout
92  * set in it's in_inact field that is decremented on each timeout
93  * and the node is reclaimed when the counter goes to zero.  We
94  * use different inactivity timeout values depending on whether
95  * the node is associated and authorized (either by 802.1x or
96  * open/shared key authentication) or associated but yet to be
97  * authorized.  The latter timeout is shorter to more aggressively
98  * reclaim nodes that leave part way through the 802.1x exchange.
99  *
100  * IEEE80211_INACT_WAIT defines node table's inactivity interval in
101  * seconds. On timeout, node table's registered nt_timeout callback
102  * function is executed. Each node in the node table has a timeout
103  * set in its in_inact field with IEEE80211_INACT_<state>. In
104  * nt_timeout function, node table is iterated and each node's
105  * in_inact is decremented. So IEEE80211_INACT_<state> is defined in
106  * the form [inact_sec]/IEEE80211_INACT_WAIT.
