.Dt IWLWIFI 4
.Os
.Sh NAME
.Nm iwlwifi
.Nd Intel IEEE 802.11a/b/g/n/ac/ax wireless network driver
.Sh SYNOPSIS
The driver will auto-load without any user interaction using
.Xr devmatch 8
if enabled in
.Xr rc.conf 5 .
.Pp
Only if auto-loading is explicitly disabled, place the following
lines in
.Xr rc.conf 5
to manually load the driver as a module at boot time:
.Bd -literal -offset indent
kld_list="${kld_list} if_iwlwifi"
.Ed
.Pp
The driver should automatically load any
.Xr iwlwififw 4
firmware needed for the particular chipset.
.Pp
It is discouraged to load the driver from
.Xr loader 8 .
.Sh DESCRIPTION
The
.Nm
driver is derived from Intel's Linux iwlwifi driver
.Pp
.Nm
will be a successor to
.Xr iwm 4
and may supersede that driver in the future.
It still complements the
.Xr iwn 4
driver which supports older chipsets.
.Pp
The driver uses the
.\" No LinuxKPI man pages so no .Xr here.
.Em linuxkpi_wlan
and
.Em linuxkpi
compat framework to bridge between the Linux and
native
.Fx
driver code as well as to the native
.Xr net80211 4
wireless stack.
.Pp
While
.Nm
supports all 802.11 a/b/g/n/ac/ax
the compatibility code currently only supports 802.11 a/b/g modes.
Support for 802.11 n/ac is to come. 802.11ax and 6Ghz support are planned.
.Sh HARDWARE
The
.Nm
driver supports PCIe devices from the
.Em mvm
sub-driver with the following chipset generations:
.Pp
.\" awk -F\\t '{ print $5 }' ~/tmp/iwlwifi_pci_ids_name.txt | \
.\" grep -v undefined | sort -V | uniq | grep -v ^$ | \
.\" awk '{ printf ".It\n%s\n", $0 }'
