According to RFC 4326 (4.1) D-bit is MSB in net-endian 16bit.
dvb_net.c did

- Add support for the PointNix Intra-Oral Camera, which required addition of
a construct for reading the "snapshot" button (provided on the em2860 and
em2880 chips, but this is the first case where I have seen it actually used
in a product). The button is wired to pin 56 on the em2880.

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.
