Hi, I am running the DPDK test suite (DTS) in a VM and I see a lot of the test cases failing when running the testpmd application
I manually run the testpmd application as follows and I see this error: test at pts00606-vm2:~/dpdk-16.04$ sudo ./ppc_64-power8-linuxapp-gcc/app/testpmd -c 1 -n 4 -- -i --max-pkt-len=9000 --port-topology=loop --txqflags=0 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 8 on socket 0 EAL: Detected lcore 2 as core 16 on socket 0 EAL: Detected lcore 3 as core 24 on socket 0 EAL: Support maximum 256 logical core(s) by configuration.
