rtwn(4), urtwn(4): merge common code, add support for 11ac devices.

Browse Source 
All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
 * for RTL8821AU: 2 VAPs at the same time;
 * other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
 * bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
 * common (if_rtwn*)
 * chip-specific (rtl*/*)
- various other bugfixes.

Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn  rtwnfw  -> rtwn rtwn_pci rtwnfw

Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.

.Nd Realtek RTL8188CE PCIe IEEE 802.11b/g/n wireless network device
.Nd Realtek IEEE 802.11 wireless network driver
.Sh SYNOPSIS
.Cd "options RTWN_DEBUG"
.Cd "options RTWN_WITHOUT_UCODE"
.Pp
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device rtwn"
.Cd "device rtwnfw"
.Cd "device rtwn_usb"
.Cd "device rtwn_pci"
.Cd "device wlan"
.Cd "device firmware"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
module at boot time, place following lines in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_rtwn_load="YES"
.Ed
.Pp
After you have read the license in
.Pa /usr/share/doc/legal/realtek.LICENSE
you will want to add the following lines to
.Xr loader.conf 5 :
.Bd -literal -offset indent
legal.realtek.license_ack=1
rtwn-rtl8192cfwU_load="YES"
rtwn-rtl8192cfwU_B_load="YES"
if_rtwn_pci_load="YES"
if_rtwn_usb_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports PCIe wireless network devices based on the Realtek
RTL8188CE chipset.
driver provides support for wireless network devices based on
the Realtek RTL8192C, RTL8188E, RTL8812A and RTL8821A programming APIs.
These APIs are used by a wide variety of chips; most chips with USB
and some with PCI interface are supported.
.Pp
The RTL8188CE 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.
To enable use for PCI/PCIe systems, see the rtwn_pci(4) driver;
for USB devices, use the rtwn_usb(4) driver.
.Pp
These are the modes the
.Nm
driver can operate in:
.Bl -tag -width "IBSS-masterXX"
.It BSS mode
Also known as
.Em infrastructure
mode, this is used when associating with an access point, through
which all traffic passes.
This mode is the default.
.It monitor mode
In this mode the driver is able to receive packets without
associating with an access point.
This disables the internal receive filter and enables the card to
capture packets from networks which it wouldn't normally have access to,
or to scan for access points.
.El
The driver supports
.Cm station ,
.Cm adhoc ,
.Cm hostap
and
.Cm monitor
mode operation.
There are no limitations for number of
.Cm monitor
mode
virtual interfaces; in addition to any other virtual interface
one
.Cm station
interface can be added (Note: RTL8821AU supports two non-monitor
mode interfaces at the same time).
.Pp
The
.Nm
driver can be configured to use
Wired Equivalent Privacy (WEP) or
Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
WPA is the current encryption standard for wireless networks.
It is strongly recommended that WEP
not be used as the sole mechanism
to secure wireless communication,
due to serious weaknesses in it.
All chips have hardware support for WEP, AES-CCM and TKIP encryption.
.Pp
The
.Nm
driver can be configured at runtime with
.Xr ifconfig 8 .
.Sh FILES
The driver needs at least version 1.0 of the following firmware files,
which are loaded when an interface is brought up:
.Bl -tag -width ".Pa /usr/share/doc/legal/realtek.LICENSE" -compact
.It Pa /usr/share/doc/legal/realtek.LICENSE
.Nm
firmware license
.El
.Pp
The driver (if not compiled with

This tunable controls how key slots are assigned:
.br
0 - disable h/w crypto support. Features that require access
to frame contents (e.g., TCP/UDP/IP Rx checksum validation)
will not work;
.br
1 - use h/w crypto support for pairwise keys only;
.br
2 - use h/w crypto support for all keys; may not work for
multi-vap configurations.
.br
By default it is set to 1.
.It Va dev.rtwn.%d.ratectl
This tunable switches between rate control implementations:
.br
0 - no rate control;
.br
1 - driver sends 'tx complete' reports to net80211; algorithm
is controlled via net80211;
.br
2 - firmware-based rate control.
.br
By default it is set to 1; however driver may choose another
algorithm in case if it is not implemented

driver supports USB 2.0 wireless network devices based on Realtek
RTL8188CUS, RTL8188CE-VAU, RTL8188EUS, RTL8188RU and RTL8192CU chipsets.
.Pp
The RTL8188CUS and RTL8188EUS are highly integrated 802.11n adapters that
combine a MAC, a 1T1R capable baseband and an RF in a single chip.
They operate 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
All chips have hardware support for WEP, AES-CCM and TKIP encryption.
.Pp
The driver supports
.Cm station ,
.Cm adhoc ,
.Cm hostap ,
and
.Cm monitor
mode operation.
Only one virtual interface may be configured at any time.
