46.Sh DESCRIPTION
47The
48.Nm net80211
49layer includes
50.Xr ddb 4
51support for displaying important data structures.
52This is especially important because wireless applications are often
53built for embedded environments where cross-machine or post-mortem
54debugging facilities like
55.Xr kgdb 1
56are infeasible.
57.Pp
58The most commonly used command is
59.Bd -literal -offset indent
60show all vaps/a
61.Ed
62.Pp
63which dumps the contents of all
64.Vt ieee80211vap ,
65.Vt ieee80211com ,
66and
67.Vt ieee80211_node
68data structures in the system.
