  netdev-dpdk: Do not flush tx queue which is shared among CPUs since it is always flushed

When tx queue is shared among CPUS,the pkts always be flush
in 'netdev_dpdk_eth_send'. So it is unnecessarily for flushing
in netdev_dpdk_rxq_recv Otherwise tx will be accessed without
locking.

  dpif-netdev: log port/core affinity

When using multiple PMDs and numerous ports, a performance gain
may be achieved in some use cases by pinning a PMD/port to a
particular (set of) core(s).

This patch provides a summary of the switch's port/core affinities
each time that the status of the switch's ports is modified.
Based on this information, a user may determine what affinity
modifications are required to optimise performance for their
particular use case.
