The staging isdn drivers are gone, and CONFIG_BT_CMTP is now the only user. This means a lot of the code in the subsystem has no remaining callers and can be removed. Change the capi user space front-end to be part of kernelcapi, and the combined module to only be compiled if BT_CMTP is also enabled, then remove the interfaces that have no remaining callers. As the notifier list and the capi_drivers list have no callers outside of kcapi.c, the implementation gets much simpler. Some definitions from the include/linux/*.h headers are only needed internally and are moved to kcapi.h.

This provides CAPI (the Common ISDN Application Programming
|
|
Interface) Version 2.0, a standard making it easy for programs to
|
|
access ISDN hardware in a device independent way. (For details see
|
|
<http://www.capi.org/>.) CAPI supports making and accepting voice
|
|
and data connections, controlling call options and protocols,
|
|
as well as ISDN supplementary services like call forwarding or
|
|
three-party conferences (if supported by the specific hardware
|
|
driver).
|
|
|
|
This subsystem requires a hardware specific driver.
|
|
See CONFIG_BT_CMTP for the last remaining regular driver
|
|
in the kernel that uses the CAPI subsystem.

If you say Y here, the kernelcapi driver can make verbose traces
|
|
of CAPI messages. This feature can be enabled/disabled via IOCTL for
|
|
every controller (default disabled).

This option will enhance the capabilities of the /dev/capi20
|
|
interface. It will provide a means of moving a data connection,
|
|
established via the usual /dev/capi20 interface to a special tty
|
|
device. If you want to use pppd with pppdcapiplugin to dial up to
|
|
your ISP, say Y here.
