From 736b30ebf27e1498d19ad6701a876e97dff90762 Mon Sep 17 00:00:00 2001 From: Declan Doherty Date: Thu, 26 Apr 2018 11:41:00 +0100 Subject: [PATCH] ethdev: add port representor device flag 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.
