-What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
-When: November 2005
-Files: drivers/pcmcia/: pcmcia_ioctl.c
-Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a
- normal hotpluggable bus, and with it using the default kernel
- infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA
- control ioctl needed by cardmgr and cardctl from pcmcia-cs is
- unnecessary, and makes further cleanups and integration of the
- PCMCIA subsystem into the Linux kernel device driver model more
- difficult. The features provided by cardmgr and cardctl are either
- handled by the kernel itself now or are available in the new
- pcmciautils package available at
- http://kernel.org/pub/linux/utils/kernel/pcmcia/
-Who: Dominik Brodowski <linux@brodo.de>
-
----------------------------
-
What: ip_queue and ip6_queue (old ipv4-only and ipv6-only netfilter queue)
When: December 2005
Why: This interface has been obsoleted by the new layer3-independent

- bind_request() and bind_device() are merged by now. Register_client()
- is called right at the end of bind_request(), during the driver's

-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.
