|
|
.Sh NAME
|
|
.Nm mt7915
|
|
.Nd MediaTek IEEE 802.11ax 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_mt7915"
|
|
.Ed
|
|
.Pp
|
|
The driver should automatically load any
|
|
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 MediaTek's Linux mt76 driver and provides support for
|
|
the following chipsets:
|
|
.Pp
|
|
.Bl -tag -width Ds -offset indent -compact
|
|
.It MediaTek MT7915E (PCIe)
|
|
.El
|
|
.Pp
|
|
This driver requires firmware to be loaded before it will work.
|
|
The package
|
|
.Pa wifi-firmware-mt76-kmod
|
|
from the
|
|
.Pa ports/net/wifi-firmware-mt76-kmod
|
|
port needs to be installed before the driver is loaded.
|
|
Otherwise no
|
|
.Xr wlan 4
|
|
interface can be created using
|
|
.Xr ifconfig 8 .
|
|
.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 and ax
|
|
the compatibility code currently only supports 802.11 a/b/g modes.
|
|
Support for 802.11 n/ac is to come.
|
|
.Sh BUGS
|
|
Certainly.
|
|

|
|

|
|
.Xr ifconfig 8 ,
|
|
.Xr wpa_supplicant 8
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in
|
|
.Fx 14.0 .
