[dpdk-dev] [PATCH v7 4/9] ethdev: Add port representor device flag

Declan Doherty declan.doherty at intel.com
Mon Apr 16 15:06:00 CEST 2018


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.
