+SR-IOV and Multistream layer 2
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
T-Rex by default only accepts packets on the receive side if the destination mac matches the
MAC address specified in the /etc/trex-cfg.yaml on the server side. For SR-IOV this creates
challenges with modifying the MAC address in the traffic profile to correctly flow packets
through specified VFs. To remove this limitation enable promiscuous mode on T-Rex to allow
all packets regardless of the destination mac to be accepted.
+This also creates problems when doing multistream at layer 2 since the source macs will be
+modified. Enable Promiscuous mode when doing multistream at layer 2 testing with T-Rex.
