29.Os
30.Sh NAME
31.Nm mt7915
32.Nd MediaTek IEEE 802.11ax wireless network driver
33.Sh SYNOPSIS
34The driver will auto-load without any user interaction using
35.Xr devmatch 8
36if enabled in
37.Xr rc.conf 5 .
38.Pp
39Only if auto-loading is explicitly disabled, place the following
40lines in
41.Xr rc.conf 5
42to manually load the driver as a module at boot time:
43.Bd -literal -offset indent
44kld_list="${kld_list} if_mt7915"
45.Ed
46.Pp
47The driver should automatically load any
48firmware needed for the particular chipset.
49.Pp
50It is discouraged to load the driver from
51.Xr loader 8 .
52.Sh DESCRIPTION
53The
54.Nm
55driver is derived from MediaTek's Linux mt76 driver and provides support for
56the following chipsets:
57.Pp
58.Bl -tag -width Ds -offset indent -compact
59.It MediaTek MT7915E (PCIe)
60.El
61.Pp
62This driver requires firmware to be loaded before it will work.
63The package
64.Pa wifi-firmware-mt76-kmod
65from the
66.Pa ports/net/wifi-firmware-mt76-kmod
67port needs to be installed before the driver is loaded.
68Otherwise no
69.Xr wlan 4
70interface can be created using
71.Xr ifconfig 8 .
72.Pp
73The driver uses the
74.\" No LinuxKPI man pages so no .Xr here.
75.Em linuxkpi_wlan
76and
77.Em linuxkpi
78compat framework to bridge between the Linux and
79native
80.Fx
81driver code as well as to the native
82.Xr net80211 4
83wireless stack.
84.Pp
85While
86.Nm
87supports all 802.11 a/b/g/n/ac and ax
88the compatibility code currently only supports 802.11 a/b/g modes.
89Support for 802.11 n/ac is to come.
90.Sh BUGS
91Certainly.
92.Sh SEE ALSO

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