Which version of GNU Radio are you using? That'll make a difference on
how easy it is to set this up.

In 3.7, we declare the enum inside of the gr::filter namespace. In the
filter_swig.i file, the firdes.h header is included using both the C++
and Swig methods to makes sure everything in it is read and processed
properly.

%{
#include "gnuradio/filter/firdes.h"
%}

%include "gnnuradio/filter/firdes.h"

If you're running 3.6, you can do similar. But check how gr_firdes.i
is written such that it redeclares the enum in SWIG.
