.Sh DESCRIPTION
|
|
The
|
|
.Nm net80211
|
|
layer includes
|
|
.Xr ddb 4
|
|
support for displaying important data structures.
|
|
This is especially important because wireless applications are often
|
|
built for embedded environments where cross-machine or post-mortem
|
|
debugging facilities like
|
|
.Xr kgdb 1
|
|
are infeasible.
|
|
.Pp
|
|
The most commonly used command is
|
|
.Bd -literal -offset indent
|
|
show all vaps/a
|
|
.Ed
|
|
.Pp
|
|
which dumps the contents of all
|
|
.Vt ieee80211vap ,
|
|
.Vt ieee80211com ,
|
|
and
|
|
.Vt ieee80211_node
|
|
data structures in the system.
