It appears that the specific issue with ToDPDKDevice is gone, but it's still very unhappy when NDESC is not defined -- now also in the FromDPDKDevice element: now, instead, it appears that when NDESC is unspecified it takes 0 and DPDK doesn't like it. Perhaps I'm missing something and you indented NDESC to be required in the conf file?
Reproducing:
./configure --enable-multithread --disable-linuxmodule --enable-intel-cpu --enable-user-multithread --verbose CFLAGS="-g -O0" CXXFLAGS="-g -std=gnu++11 -O0" --disable-dynamic-linking --enable-poll --enable-bound-port-transfer --with-netmap=no --enable-zerocopy --disable-dpdk-pools --enable-dpdk --disable-batch
conf file: FromDPDKDevice(0) -> ToDPDKDevice(0);
run : sudo userlevel/click -c 0x1 -n 1 -- -f ...

Solved by 117e017 , the default value is set in the To/FromDPDK device in mainline click but wasn't set there in fastclick ,so retrieving the patch as is lead to loose the default value.
Fixed, thanks again !
