v4l2 field types

Re: http://v4l2spec.bytesex.org/spec/x6386.htm

Is there a v4l2_field if the capture hardware does the "de-interlacing" 
to compensate for motion artifacts for full size NTSC/PAL video?

Our hardware has 2 modes for full size.  One where it outputs the top 
and bottom fields interlaced without modification(default 2255 setting). 
  The other where it compensates for motion by removing "comb" or 
"feathering" artifacts in the hardware.  This second mode still 
transmits both fields at the same time interlaced in one buffer.

Sorry, please ignore this question re spec. 0.24.  I found the 
V4L2_MODE_HIGHQUALITY definition.  It's not ideal, however, because 
there may be different algorithms implemented (or desired) to remove the 
artifacts.
