I do have one suggestion: media_v2_interface, media_v2_pad and media_v2_link all
have a 'flags' field, but it is not clear from the code in the header which flag
#defines are used for which struct. Perhaps a few comments would help with that.

Strange odd number here for no clear reason. Perhaps use 8 or 10 instead?
Anyway, you have my Ack.
