I think it is better to stick to simply change the generated file between "make config" and "make" for the documentation.

The way I have been changing the default configuration options is to copy the config/defconfig_XYZ file like defconfig_x86_64-native-linuxapp-gcc to a new name say defconfig-x86_64-qat-linuxapp-gcc. Then edit that file and add the CONFIG_RTE_LIBRTE_PMD_QAT=y to the bottom of the file. Then ?make install T=x86_64-qat-linuxapp-gcc -j?.
