It looks like an issue with the BNXT DPDK driver, it seems the device is trying to write at address 0 and the IOMMU rightfully complains. The Mellanox DPDK driver uses a completely different infrastructure (RDMA) so it is not surprising it works while BNXT does not. Does the BNXT device works with DPDK testpmd? Also, could you share the output of 'vppctl sh dpdk version', 'vppctl sh hard', 'vppctl show err', 'vppctl sh pci' and 'vppctl sh log'? best ben
