32.Os
33.Sh NAME
34.Nm iwlwifi
35.Nd Intel IEEE 802.11a/b/g/n/ac/ax wireless network driver
36.Sh SYNOPSIS
37The driver will auto-load without any user interaction using
38.Xr devmatch 8
39if enabled in
40.Xr rc.conf 5 .
41.Pp
42Only if auto-loading is explicitly disabled, place the following
43lines in
44.Xr rc.conf 5
45to manually load the driver as a module at boot time:
46.Bd -literal -offset indent
47kld_list="${kld_list} if_iwlwifi"
48.Ed
49.Pp
50The driver should automatically load any
51.Xr iwlwififw 4
52firmware needed for the particular chipset.
53.Pp
54It is discouraged to load the driver from
55.Xr loader 8 .
56.Sh DESCRIPTION
57The
58.Nm
59driver is derived from Intel's Linux iwlwifi driver and provides support for
60all chipsets supported by the
61.Em mvm
62part of that driver.
63.\" XXX-BZ find way to add full list of chipsets automatically
64.Nm
65will be a successor to
66.Xr iwm 4
67and may superseed that driver in the future.
68It still complements the
69.Xr iwn 4
70driver which supports older chipsets.
71.Pp
72The driver uses the
73.\" No LinuxKPI man pages so no .Xr here.
74.Em linuxkpi_wlan
75and
76.Em linuxkpi
77compat framework to bridge between the Linux and
78native FreeBSD driver code as well as to the native
79.Xr net80211 4
80wireless stack.
81.Pp
82While
83.Nm
84supports all 802.11 a/b/g/n/ac/ax
85the compatibility code currently only supports 802.11 a/b/g modes.
86Support for 802.11 n/ac is to come. 802.11ax and 6Ghz support are planned.
87.Sh BUGS
88Certainly.
