In Ubuntu Xenial, driver path is installed to RPATH on testpmd. This allows librte_eal.so to find drivers by using the RPATH. However, in Ubuntu Bionic, driver path is installed to RUNPATH instead. The RUNPATH on testpmd is not available by librte_eal.so and therefore lead to driver load failure: EAL: Detected 32 lcore(s) EAL: Detected 1 NUMA nodes EAL: librte_mempool_ring.so: cannot open shared object file: No such file or directory EAL: FATAL: Cannot init plugins EAL: Cannot init plugins Add 'drivers' into LD_LIBRARY_PATH so that testpmd can find and make use of these shared libraries.
