At present, the system-dpdk-testsuite makes assumptions about environment configuration, and will error out if DPDK compatible interfaces not configured for DPDK are present in the system with a message like: EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:03.0 (socket -1) eth_virtio_pci_init(): Failed to init PCI device EAL: Requested device 0000:00:03.0 cannot be used The system-dpdk-testsuite is useful even with no DPDK PHY available, as the tests requiring a PHY will skip gracefully when none present. This patch extends the OVS_DPDK_START and OVS_DPDK_START_VSWITCHD macros to allow passing in values that will be set in `other_config:dpdk-extra` before the test runs. Tests that do not use physical ports are also extended to pass the `--no-pci` argument. We will use this patch in a follow-up, enabling more elaborate Debian autopkgtests for Open vSwitch.
