According to RFC 4326 (4.1) D-bit is MSB in net-endian 16bit.
dvb_net.c did
				/* Set D-bit for CRC32 verification,
				 * if it was set originally. */
				ulen |= 0x0080;
which works of little-endian (htons(1<<15) is 0x0080 there), but breaks
on big-endian.

V4L2_CID_PRIVATE_BASE controls are not allowed when called from
VIDIOC_S/G_EXT_CTRL as extended controls use a better mechanism
for private controls. But still allow it when called from the

matched cx18_gpio() values for tuner, line in 1, and radio and added LED

The xc5000 firmware download process can be slow on certain devices.

Add a module option, "init_fw" to perform the firmware download during
xc5000_attach(), which would get the firmware download over with well
before any tune request is made.

When this option is enabled, it will reduce the time it takes to get a
signal lock during the first tune after driver load, but will add a few
seconds to the driver initialization.

The IVTV_IOC_DMA_FRAME ioctl fails to correctly 'start' the decoder. Although
yuv output will be correct, some functions which should be disabled while the
decoder is in use remain enabled. This can result in hardware registers being
corrupted, causing problems with the mpeg decoder. This patch ensures the
decoder 'start' sequence is called, disabling these functions until the
device is closed.

If the capture is scaled, then the video_temporal_filter is set to 0
by the cx2341x.c module since otherwise you would get ghosting.

However, this was also done in the VIDIOC_S_FMT ioctl which meant that
the video_temporal_filter control was reset to 0 or 8 each time S_FMT
was called. This was old code that should have been removed a long time
ago.

A number of V4L drivers have a mod param to specify their preferred minors.
This is because it is often desirable for applications to have a static /dev
name for a particular device.  However, using minors has several disadvantages:

  1) the requested minor may already be taken
  2) using a mod param is driver specific
  3) it requires every driver to add a param
  4) requires configuration by hand

This patch introduces an "index" attribute that when combined with udev rules
can create static device paths like this:

/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0
/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video1
/dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video2

$ ls -la /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0
lrwxrwxrwx 1 root root 12 2008-04-28 00:02 /dev/v4l/by-path/pci-0000:00:1d.2-usb-0:1:1.0-video0 -> ../../video1

These paths are steady across reboots and should be resistant to rearranging
across Kernel versions.

video_register_device_index is available to drivers to request a
specific index number.
