HardenedBSD/sys/net80211/ieee80211_ddb.c
Monthadar Al Jaberi b5df85a6fd Implemented so that Mesh forwarding information lifetime is dynamic. 
* Introduced ieee80211_mesh_rt_update that updates a route with the
 maximum(lifetime left, new lifetime);
 * Modified ieee80211_mesh_route struct by adding a lock that will be used
 by both ieee80211_mesh_rt_update and precursor code (added in future commit);
 * Modified in ieee80211_hwmp.c HWMP code to use new ieee80211_mesh_rt_update;
 * Modified mesh_rt_flush_invalid to use new ieee80211_mesh_rt_update;
 * mesh_rt_flush also checks that lifetime == 0, this gives route discovery
 a change to complete;
 * Modified mesh_recv_mgmt case IEEE80211_FC0_SUBTYPE_BEACON:
 when ever we received a beacon from a neighbor we update route lifetime;

* Channel state:
*
* ic_channels is the set of available channels for the device;
* it is setup by the driver
* ic_nchans is the number of valid entries in ic_channels
* ic_chan_avail is a bit vector of these channels used to check
* whether a channel is available w/o searching the channel table.
* ic_chan_active is a (potentially) constrained subset of
* ic_chan_avail that reflects any mode setting or user-specified
* limit on the set of channels to use/scan
* ic_curchan is the current channel the device is set to; it may
* be different from ic_bsschan when we are off-channel scanning
* or otherwise doing background work
* ic_bsschan is the channel selected for operation; it may
* be undefined (IEEE80211_CHAN_ANYC)
* ic_prevchan is a cached ``previous channel'' used to optimize
* lookups when switching back+forth between two channels
