Install the SRPMs if you want to modify the spec files before building Napatech driver and tools RPMs.
Steps
To install the SRPMs:
$ rpm --install nt-driver-3gd-x.y.z.build-short-sha1.src.rpm $ rpm --install nt-tools-3gd-x.y.z.build-short-sha1.src.rpm
Results
This will by default install the source RPMs in ~/rpmbuild. For example:
rpmbuild

│ └── nt_tools_3gd_linux_3.8.0.302-f4d297.tar.gz
└── SPECS
