28.Sh NAME
29.Nm mt7915
30.Nd MediaTek IEEE 802.11ax wireless network driver
31.Sh SYNOPSIS
32The driver will auto-load without any user interaction using
33.Xr devmatch 8
34if enabled in
35.Xr rc.conf 5 .
36.Pp
37Only if auto-loading is explicitly disabled, place the following
38lines in
39.Xr rc.conf 5
40to manually load the driver as a module at boot time:
41.Bd -literal -offset indent
42kld_list="${kld_list} if_mt7915"
43.Ed
44.Pp
45The driver should automatically load any
46firmware needed for the particular chipset.
47.Pp
48It is discouraged to load the driver from
49.Xr loader 8 .
50.Sh DESCRIPTION
51The
52.Nm
53driver is derived from MediaTek's Linux mt76 driver.
54.Pp
55This driver requires firmware to be loaded before it will work.
56The package
57.Pa wifi-firmware-mt76-kmod
58from the
59.Pa ports/net/wifi-firmware-mt76-kmod
60port needs to be installed before the driver is loaded.
61Otherwise no
62.Xr wlan 4
63interface can be created using
64.Xr ifconfig 8 .
65.Pp
66The driver uses the
67.\" No LinuxKPI man pages so no .Xr here.
68.Em linuxkpi_wlan
69and
70.Em linuxkpi
71compat framework to bridge between the Linux and
72native
73.Fx
74driver code as well as to the native
75.Xr net80211 4
76wireless stack.
77.Pp
78While
79.Nm
80supports all 802.11 a/b/g/n/ac and ax
81the compatibility code currently only supports 802.11 a/b/g modes.
82Support for 802.11 n/ac is to come.
83.Sh HARDWARE
84The
85.Nm
86driver supports PCIe devices with the following chipsets:

90.El
91.Sh BUGS
92Certainly.

97.Sh HISTORY
98The
99.Nm
100driver first appeared in
101.Fx 14.0 .
