Moacyr,

Take a look at the v4l-utils tree. There are some parsers there for some common sniffer
formats, at the utils dirs, and a parser for em28xx format. You may eventually need to 
write a new parser, if your sniffer has a different format.

Of course, you can just try to search for the changes at the GPIO registers, but doing
it manually may be very time-consuming.

Cheers,
Mauro
