ieee80211_bmiss(9)
The software layer provides a support framework for drivers that
includes handling beacon miss events in station mode. Drivers
can dispatch beacon miss events that are recognized in hardware
or can detect beacon miss if the driver dispatches received bea‐
con frames through the normal receive path. Software beacon miss
support is especially useful when multiple vaps are operating and
any hardware beacon miss support is not available (e.g. operating
as an access point together with one or more station mode vaps).
Drivers should dispatch beacon miss events recognized in the dri‐
ver with This causes some number of ProbeRequest frames to be
sent to the access point to check if the association is still
alive. If no response is received and roaming mode is set to
then will try to re-associate and if that fails trigger a scan to
look for the access point or another suitable AP. When the state
machine is being operated manually, e.g. by then applications are
notified of the state change and are responsible for handling the
work of scanning for a new access point. The number of beacon
miss events (without a ProbeResponse) is user settable with the
request. Software beacon miss detection is enabled per-vap by
setting the flag. Typically this is done when a vap is setup
when the option is supplied to the clone operation. But drivers
may also force this when they know they need help detecting bea‐
con miss. When beacon miss is detected in software the event is
dispatched without driver involvement. Note that software beacon
miss handling is not limited to station mode; it can be used in
any operating mode where beacons from a peer station are re‐
ceived.
