Does someone face the same issue? In my environment, It seems almost all DPDK apps (at lease l2fwd and testpmd) cannot work. -------------------------------------------- EAL: Support maximum 128 logical core(s) by configuration. EAL: Detected 8 lcore(s) EAL: cannot open VFIO container, error 2 (No such file or directory) EAL: VFIO support could not be initialized EAL: Setting up memory...

"eal: fix check for power of 2 in 0 case". Thanks, Tetsuya
