27.Sh NAME
28.Nm rtwnfw
29.Nd "Firmware Module for Realtek Wireless driver"
30.Sh SYNOPSIS
31To compile this module into the kernel,
32place the following line in your
33kernel configuration file:
34.Bd -ragged -offset indent
35.Cd "device rtwnfw"
36.Ed
37.Pp
38This will include all firmware images inside the kernel.
39If you want to pick only the firmware image for your network adapter choose one
40of the following:
41.Bd -ragged -offset indent
42.Cd "device rtwn-rtl8188eefw"
43.Cd "device rtwn-rtl8188eufw"
44.Cd "device rtwn-rtl8192cfwE_B"
45.Cd "device rtwn-rtl8192cfwE"
46.Cd "device rtwn-rtl8192cfwT"
47.Cd "device rtwn-rtl8192cfwU"
48.Cd "device rtwn-rtl8192eufw"
49.Cd "device rtwn-rtl8812aufw"
50.Cd "device rtwn-rtl8821aufw"
51.Ed
52.Pp
53Alternatively, to load all firmware images as a
54module at boot time, place the following line in
55.Xr loader.conf 5 :
56.Bd -literal -offset indent
57rtwn-rtl8188eefw_load="YES"
58rtwn-rtl8188eufw_load="YES"

67.Sh DESCRIPTION
68rtwn-rtl8192cfwE and rtl8192cfwE_B modules provide access
69to firmware sets for the Realtek RTL8188CE chip based PCIe adapters.
70rtwn-rtl8188ee module provides access to firmware sets for the
71Realtek RTL8188EE chip based PCIe adapters.
72Other modules provide access to firmware sets for the Realtek RTL8188CUS,
73RTL8188CE-VAU, RTL8188EUS, RTL8188RU, RTL8192CU, RTL8192EU, RTL8812AU and
74RTL8821AU chip based USB WiFi adapters.
75They may be
76statically linked into the kernel, or loaded as a modules.
