Based on some feedback clarify the man page for - how to load the driver currently - status of the driver with respect to iwm(4) and leave a comment to (automatically) add a full list of chipsets to the man page.

.Os
|
|
.Sh NAME
|
|
.Nm iwlwifi
|
|
.Nd Intel IEEE 802.11a/b/g/n/ac/ax wireless network driver
|
|
.Sh SYNOPSIS
|
|
To load the driver as a module at boot time, place the following lines in
|
|
.Xr rc.conf 5 :
|
|
.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 in that case.
|
|
.Pp
|
|
It is anticipated that the driver will support auto-loading via
|
|
.Xr devmatch 8
|
|
in the future and will need no configuration at all.
|
|
.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 and provides support for
|
|
all chipsets supported by the
|
|
.Em mvm
|
|
part of that driver.
|
|
.\" XXX-BZ find way to add full list of chipsets automatically
|
|
.Nm
|
|
will be a successor to
|
|
.Xr iwm 4
|
|
and may superseed 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 FreeBSD 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 BUGS
|
|
Certainly.
