dpdk-pdump cannot init tailq as secondary process

[Karim Harouat]

Hello

I'm using dpdk version 22.11 and so the arg --proc-type secondary is set 
hardcoded inside the dpdk-pdump main program.

I fixed my issue by taking all cflags in libdpdk.pc file linking any 
personnal application statically with all librte.

And so the static rte_fib tail is initialized properly for the 
dpdk-pdump. But my app is bigger now, I'm currently trying to link only 
needed libraries to reduce the size.

With less libraries static linkage now I am facing with another issue,  
it is create ring vdev function which failed.

I will try dpdk-dumpcap

Thank you!
