However the VLAN will not be a part of the RSS hash. The only components of the hash are the IPv4/IPv6 source and destination addresses, and if the flow is TCP then the port numbers. I would recommend testing with something like the "netperf -t TCP_CRR" test which should open a number of ports and spread traffic out between multiple queues.
