This implies processing of headers/footers in kernel space to some generic format.
It might work, but sometimes there might be an unwanted performance loss. However
I wouldn't expect it to be that significant, depends on how the format of an 
embedded data from the sensor looks like. Processing 4KiB of data could be 
acceptable.

I'm assuming here, we want to convert the frame embedded (meta) data for each 
sensor to some generic description format ? It would have to be then relatively 
simple, not to increase the frame header size unnecessarily.
