[dpdk-dev] [PATCH v8 4/9] ethdev: Add port representor device flag

[Declan Doherty]

Add new device flag to specify that an ethdev port is a port representor.
Extend rte_eth_dev_info structure to expose device flags to the user which
enables applications to discover if a port is a representor port.
