No, it should not. dgap_parsefile() is executing a loop and reading
tokens from the configuration file and depending on what token it has
read it will do switch-case. And it will not find case IO: anymore and
will be just ignored (there is no default:).

And this is actually just a first step towards removing the
configuration file as Greg was telling that loading a firmware file and
consideing it as a configuartion file is not the right thing to do. So I
am removing all the unused configurations one at a time and after they
are removed then depending on the configurations left I will ask for
your suggestion how to remove the use of configuration file.
