From 5d08ffdf317d31361a528bf1b6d33cd4d0007600 Mon Sep 17 00:00:00 2001 From: Christian Trautman Date: Mon, 25 Sep 2017 17:22:38 -0400 Subject: trex_prom: Add promiscuous option for trex for SRIOV tests Adds option to enable promiscuous mode for Trex traffic generator to allow for SR-IOV tests to work correctly. Trex by default only accepts packets based on destination MAC address matching what is configured on server in /etc/trex-cfg.yaml. This removes that limitation since SR-IOV tests require mac addresses to be modified in the generated packets to correctly route packets to the relevant VFs.
