Hi! This is my first attempt to use DPDK on POWER8 machine and yet unsuccessful as it turned out DPDK only supports IB-Mellanox (I only got ethernet-Mellanox, and requires OFED), rmmod on Intel 40Gb module produces PCI errors (unrelated to DPDK) and Broadcom bnx2x has few issues (below) and still crashes as I suspect I got DMA mapping wrong, here is a backtrace:
