27.Os
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 and provides support for
54the following chipsets:
55.Pp
56.Bl -tag -width Ds -offset indent -compact
57.It MediaTek MT7915E (PCIe)
58.El
59.Pp
60This driver requires firmware to be loaded before it will work.
61The package
62.Pa wifi-firmware-mt76-kmod
63from the
64.Pa ports/net/wifi-firmware-mt76-kmod
65port needs to be installed before the driver is loaded.
66Otherwise no
67.Xr wlan 4
68interface can be created using
69.Xr ifconfig 8 .
70.Pp
71The driver uses the
72.\" No LinuxKPI man pages so no .Xr here.
73.Em linuxkpi_wlan
74and
75.Em linuxkpi
76compat framework to bridge between the Linux and
77native
78.Fx
79driver code as well as to the native
80.Xr net80211 4
81wireless stack.
82.Pp
83While
84.Nm
85supports all 802.11 a/b/g/n/ac and ax
86the compatibility code currently only supports 802.11 a/b/g modes.
87Support for 802.11 n/ac is to come.
88.Sh BUGS
89Certainly.

94.Sh HISTORY
95The
96.Nm
97driver first appeared in
98.Fx 14.0 .
