New Revision: 251538
URL: http://svnweb.freebsd.org/changeset/base/251538
Log:
Import Kevin Lo's port of urtwn(4) from OpenBSD. urtwn(4) is a driver for the
Realtek RTL8188CU/RTL8192CU USB IEEE 802.11b/g/n wireless cards.
This driver requires microcode which is available in FreeBSD ports:
net/urtwn-firmware-kmod.
Hiren ported the urtwn(4) man page from OpenBSD and Glen just commited a port
for the firmware.
TODO:
- 802.11n support
- Stability fixes - the driver can sustain lots of traffic but has trouble
coping with simultaneous iperf sessions.
- fix debugging
MFC after: 2 months
Tested by: kevlo, hiren, gjb

+.Sh NAME
+.Nm urtwn
+.Nd Realtek RTL8188CU/RTL8192CU USB IEEE 802.11b/g/n wireless network device
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device ehci"
+.Cd "device uhci"
+.Cd "device ohci"
+.Cd "device usb"
+.Cd "device urtwn"
+.Cd "device wlan"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+if_urtwn_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver supports USB 2.0 wireless network devices based on Realtek
+RTL8188CUS, RTL8188CE-VAU, RTL8188RU and RTL8192CU chipsets.
+.Pp
+The RTL8188CUS is a highly integrated 802.11n adapter that combines
+a MAC, a 1T1R capable baseband and an RF in a single chip.
+It operates in the 2GHz spectrum only.
+The RTL8188RU is a high-power variant of the RTL8188CUS.
+The RTL8188CE-VAU is a PCI Express Mini Card adapter that attaches
+to the USB interface.
+.Pp
+The RTL8192CU is a highly integrated multiple-in, multiple-out (MIMO)
+802.11n adapter that combines a MAC, a 2T2R capable baseband and an
+RF in a single chip.
+It operates in the 2GHz spectrum only.
+.Pp
+The driver needs at least version 1.1p0 of the following firmware files,
+which are loaded when an interface is attached:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It urtwn-rtl8192cfwT
+.It urtwn-rtl8192cfwU
+.It urtwn-rtl8723fw
+.El
+.Pp
+The firmware is available as part of the FreeBSD Ports collection in
+net/urtwn-firmware-kmod.
+.Sh HARDWARE
+The following adapters should work:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It Belkin F7D1102 Surf Wireless Micro
+.It Edimax EW-7811Un
+.It Netgear WNA1000M
+.It Realtek RTL8192CU
+.It Realtek RTL8188CUS
+.El
+.Sh EXAMPLES
+Join an existing BSS network (i.e., connect to an access point):
+.Bd -literal -offset indent
+ifconfig wlan create wlandev urtwn0 inet 192.168.0.20 \e
+ netmask 0xffffff00
+.Ed
+.Pp
+Join a specific BSS network with network name
+.Dq Li my_net :
+.Pp
+.Dl "ifconfig wlan create wlandev urtwn0 ssid my_net up"
+.Pp
+Join a specific BSS network with 64-bit WEP encryption:
+.Bd -literal -offset indent
+ifconfig wlan create wlandev urtwn0 ssid my_net \e
+ wepmode on wepkey 0x1234567890 weptxkey 1 up
+.Ed
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "urtwn%d: error %d, could not read firmware %s"
+For some reason, the driver was unable to read the microcode file from the
+filesystem.
+The file might be missing or corrupted.
+.It "urtwn%d: device timeout"
+A frame dispatched to the hardware for transmission did not complete in time.
+The driver will reset the hardware.
+This should not happen.
