Subject[PATCH kmod 2/3] build: add relevant features to KMOD_FEATURES in config.h
Date
From: Lucas De Marchi <lucas.demarchi@intel.com>

Not all the features (i.e. those available in --enable-* or --with-*)
are really relevant to the final user. Create a KMOD_FEATURES definition
in config.h containing these features.
