isdn/gigaset: remove EXPERIMENTAL tag from GIGASET_CAPI

The CAPI variant of the Gigaset drivers can, in combination with
capidrv, now fully replace the legacy ISDN4Linux variant. All
reported problems have been fixed. So remove the EXPERIMENTAL tag
from the Kconfig option selecting it, and adapt the documentation
accordingly to encourage users to switch to it.

Impact: documentation/status update, no functional change

--------
The driver works with ISDN4linux and so can be used with any software
which is able to use ISDN4linux for ISDN connections (voice or data).
Experimental Kernel CAPI support is available as a compilation option.
The driver works with the Kernel CAPI subsystem as well as the old
ISDN4Linux subsystem, so it can be used with any software which is able
to use CAPI 2.0 or ISDN4Linux for ISDN connections (voice or data).

2.3. ISDN4linux
----------
This is the "normal" mode of operation. After loading the module you can
set up the ISDN system just as you'd do with any ISDN card supported by
the ISDN4Linux subsystem. Most distributions provide some configuration
utility. If not, you can use some HOWTOs like
http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html
If this doesn't work, because you have some device like SX100 where
debug output (see section 3.2.) shows something like this when dialing
CMD Received: ERROR
Available Params: 0
Connection State: 0, Response: -1
gigaset_process_response: resp_code -1 in ConState 0 !
Timeout occurred
you probably need to use unimodem mode. (see section 2.5.)
2.4. CAPI
2.3. CAPI
----
If the driver is compiled with CAPI support (kernel configuration option
GIGASET_CAPI, experimental) it can also be used with CAPI 2.0 kernel and
user space applications. For user space access, the module capi.ko must
be loaded. The capiinit command (included in the capi4k-utils package)
does this for you.
The CAPI variant of the driver supports legacy ISDN4Linux applications
via the capidrv compatibility driver. The kernel module capidrv.ko must
be loaded explicitly with the command
GIGASET_CAPI) the devices will show up as CAPI controllers as soon as the
corresponding driver module is loaded, and can then be used with CAPI 2.0
kernel and user space applications. For user space access, the module
capi.ko must be loaded.
Legacy ISDN4Linux applications are supported via the capidrv
compatibility driver. The kernel module capidrv.ko must be loaded
explicitly with the command
modprobe capidrv
if needed, and cannot be unloaded again without unloading the driver
first. (These are limitations of capidrv.)
The note about unimodem mode in the preceding section applies here, too.
2.5. Unimodem mode
-------------
This is needed for some devices [e.g. SX100] as they have problems with
the "normal" commands.
Most distributions handle loading and unloading of the various CAPI
modules automatically via the command capiinit(1) from the capi4k-utils
package or a similar mechanism. Note that capiinit(1) cannot unload the
Gigaset drivers because it doesn't support more than one module per
driver.
If you have installed the command line tool gigacontr, you can enter
unimodem mode using
gigacontr --mode unimodem
You can switch back using
gigacontr --mode isdn
2.4. ISDN4Linux
----------
If the driver is compiled without CAPI support (native ISDN4Linux
variant), it registers the device with the legacy ISDN4Linux subsystem
after loading the module. It can then be used with ISDN4Linux
applications only. Most distributions provide some configuration utility
for setting up that subsystem. Otherwise you can use some HOWTOs like
http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html
You can also put the driver directly into Unimodem mode when it's loaded,
by passing the module parameter startmode=0 to the hardware specific
module, e.g.
modprobe usb_gigaset startmode=0
or by adding a line like
options usb_gigaset startmode=0
to an appropriate module configuration file, like /etc/modprobe.d/gigaset
or /etc/modprobe.conf.local.
2.5. Unimodem mode

(the /dev/ttyGU0, ... mentioned above) which understands the commands
