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. JIRA: VSPERF-531 Change-Id: I19b64f364c8a1b656994c82c96f47a68b92486d8 Signed-off-by: Christian Trautman <ctrautma@redhat.com>
